Upshot Archery's Scythian bows have the most accurate shape of any low-end Scythian bow I've seen: a more angular profile than the popular Grozer Old Scythian, they also have the asymmetric shape seen on many period bows but rare on the replica market, and appear to have thicker limbs. Being made of PVC, they're extremely cheap, even at the regular price of US$100.
I am not sure how well the faux birch bark finish would pass inspection at any given reenactment event, though I expect it would be fine at Amphictyonia, and in my opinion the profile more than makes up for any possible drawback in that regard. The two pieces currently available, as well as the one in the review below, are only 30 and 35 pounds, so it may be that Upshot focuses on low draw weights for this model.
The listed strung length of 52 and 55 inches/132 and 140cm make it somewhat larger than the Grozer and it will obviously require a larger gorytos because of that. (Personally I've been hoping to find a smaller bow...)
