Yep, that train left the station. WASRs, M10s, AMDs, SAIGAs, and a few kit-builds are about all that is out there anymore in that price range. See Centerfire and Classic, local funshows for the $5XX.00 WASRs if there are any left. Watch classifieds closely.
Avoid any leftover Tantals you might find as cheap 5.45x39 and "AK74" mags are/have dissappeared.
