I think this is about as complete as I have time for, but I may come back and add more if anything particularly catches my eye.
So, after years in the hobby I find myself with hundreds of bookmarks on my computer, at a conservative estimate, of alternative miniatures and the companies that produce them. At this point it may be considered something of an obsession. Now if only I had the thousands of dollars I'd need to buy even half on them! Alas, college isn't cheap and doesn't leave me with quite the budget I'd wish. I figure it's about time I put together something that encompasses a general outline to what is out there for alternative high elves and hopefully you all can kick in and point me toward manufactures and minis that I haven't managed to stumble upon yet.
First off,
MonstersEaglesGamezone Great Eagle IGamezone Great Eagle IIGamezone Great Eagle IIIReaper Great EagleGW LotR range Great EagleRidden EaglesGamezone Sylvan Elf Wind Rider, oddly enough I can't find it on the main site, but maelstrom stocks it.
CMON Elf Sorceress on Giant Owl, only 1 left so get it while it's hot.
CMON Elf Hero on Great Eagle, out of stock now, but they pop up on ebay (there's 2 there now).
Dark Sword War Eagle with Female Elven RiderEagle alternatives (aka, small dragons)Reaper Young Fire DragonReaper Pathfinder Red DragonReaper Young Ice DragonReaper Halfling on Dragon, which is rather small (2 inches tall), but I like the sculpt.
Reaper Young Swamp DragonReaper Guardian Beast, actually an armoured, winged lion, but pretty unique and awesome. Maybe somebody with a Chrace army will indulge me and paint one up.
Reaper Silver Dragon, a bit large for an eagle, a bit small for a star dragon.
Gamezone PegasusViking Forge Wyvern, looks average but has the advantage of being really cheap ($6.95). The problem is that ordering from Viking Forge is a pain and involves mailing them a check...
Mithril Scatha the Worm, I really like this one.
Mithril Cold Drake of the Withered HeathDark Sword Black Dragon, which is at that awkward size between eagle and star dragon, but it's a good sculpt.
GW Dragonmaster Dragon (it's a little bit larger than a great eagle
link for size comparison). I can't link the store for some reason, but you should be able to find it on the GW site.
GW Drakes, if you must stay with GW only models for their stores or some such. However, the drakes are smaller than the eagles, more on the size of the old warhawks.
GriffonsGamezone Veteran GriffonCavalcade/Dragonblood GriffonCMON Griffon Commander, the largest and most awesome griffon ever made. If you want a centerpiece griffon for you army, this is it.
Titan Forge Griffon LadyDragons, full-sized to downright huge!Reaper Kyra & LavarathReaper Gauth, 12" tall and and a 16" wingspan
Valiant Greater Dragon: totally huge, like 2' tall
Valiant RazorwingForge World Carmine Dragon, I have one and it's awesome. I'll post up some pictures and size comparisons once I have it all put together and painted up. It's about the same size as the high elf dragon.
Forge World Fire DragonMithril The Vengeance of SmaugIron Wind/Ral Partha, T char: Dragon of Flame and Fury. It's a terrible picture, but it's a nice dragon.
PaintedMantic Elf Lord on Battle DragonConfrontation Titan Dragon, very large.
Dark Sword Red DragonDark Sword Elmore Dragon 1, Mountain ConflictDark Sword Elmore Dragon 3, Golden Dragon of ChaosDark Sword Elmore Dragon 4, Strange CompanionsDark Sword Elmore Dragon 5,, my favorite of the Elmore set.
Dark Sword Red Dragon 2, this one is quite large.
Ultraforge DragonHeresy Dragon, which is huge and wonderful, but has a waiting list something like a year long...
CMON Cang the Implacable, this one deserves a picture:

Iron Wind is re-releasing a good chunk of the old Ral Partha dragons
here. They're pretty cheap, though I don't like too many of them. If you want to see some decent photos of painted versions go to
this guy's site and navigate to the dragon gallery.
McFarlane toys are always worth mentioning when talking about dragons. You can find some
here. They are out of production, but still pretty cheap and easy to find.
I will continue to add as things occur to me. Hope all that junk helps someone find a model they're looking for!
