the most beautiful ones may not be the ones in resin, already painted, newline/weta copyrighted ones… Those are the most expensives… but you can have very beautiful ones at 50€
Andrea is also making a dragon rider in 54mm scale (belpheegor on dragon) and as far as I know it is white metal, unprimed, unpainted but huge (imagine a dragon and its rider in 54mm)…. for 168€ (the price is fair, for so much metal and detail) http://www.andreaeurope.com/fotos/andrea/Warlord-Saga/detallegran/WSS-03-01.jpg
I also do like dragon-figures very much, but I’m lacking the space to display such huge figures. And yes, a bit expensive many of them are, though one has to consider sculpting, production and material as Master Gildor pointed out.
