The only solid SL piece in sub 1k 2nd-hand market is going to be Brno ZP series gun, but these are more in fowler category. So it boils down to "Uplandish" IG gun, Poldihutte steel barreled Brno, good ole' L.C. Smith or....some junkish Italian or Spanish clunker.

Here is what 'Funeralish' Czech ZP series gun looks like. This might be Jugo ZCZ piece, but who knows? Anyway it's twin of ZP bro gun.
