I bought the Altaya Buffalo recently via a Spanish seller on eBay. Altaya prices are generally becoming more realistic now as more IXO gets released here in the USA, and mine cost about what they will when the come stateside via IXO - $20, plus a reasonable $8 to ship here from Spain.
For anyone interested, Squadron.com has Finnish decals on sale right now (through Oct 31) and I got the Bf-109 set (AU7003, just 49¢!!) to decal my Buffalo. Check it out - sure makes for one handsome little bird (one of Altaya/IXO's best IMHO....)
(And by the way, the Finns did very well vs the Russians with this little machine....)
