I've dealt with DSA and really liked them. A lot of companies are difficult to deal with after the sale. Not these guys. Springfield is really good too.Personnally I would build my own.I really have only seen two collectable FAL's, and for that reason I consider them non-collectable. It is a shooters rifle, and some of the different pieces that I prefer are English(furniture,folding cocking handle,lower receiver and parts) Israeli(fold up buttplate,heavy barrel cut down for carbine,mags, mag release) Belgium,(furniture, light barrel, upper receiver,sights).South African(folding stock)
There's a perfect mix for every rifle, but it usually includes a part or two from another variant.Find somebody thats really into them and has a few variants on hand before you buy.
