I really miss the low priced kits, going from gun show to gun show looking for just the right kit.
My lowest cost build was a Romy "G" I picked the kit up for $40 because of missing parts (the trigger guard) he was selling the full kits for $50. I picked up a trigger guard for $4 at a local show. I had some rusty flats I got for $5 ea. & a few other parts to put together for a total build price of about $80.
I got into that Bulgarian AK74 kit buy for $115.00 that Nick710 talked about, I bought four of them.
I built one & held onto the other three until just before Christmas, then sold them that paid for the kids christmas that year.
I still have a few odd kits that I'm holding onto for a rainy day.
The best buy on a kit now days I think is from AK Builder. It is hard to beat a kit with a head spaced, populated barrel.
I wouldn't call it a "screaming deal" but it is low enough to still be fun building.
