The only SMLE type weapons I've seen at shows in Pennsylvania, Maryland and Virginia for $80 - 90 where Khyber Pass copies, which are excreable abortions of pallet wood for stocks and train rails for receivers. Unsporterized Ishapores continue to hover around twice that sum, and are noticably different.

This page on the Khyber copies of the Martini is a good primer on what to look out for with the Darra-made copies of the Enfield. http://www.martinihenry.com/khyberpage.html
