Seems like whenever a good deal comes about, they're all gone within 4-5 hours. (Example: The Polish Underfolders that sold out @ Cope's the other night). Freak'n gun vultures buying 'em up and slapping them up on Gunbroker a few months later... I'd telephone some of these places and ask if they're going to be receiving any new inventory any time soon. Occasionally you'll get someone on the line who answers the telephone that will give you a hint as to when something will come in. When it comes in, jump on it. (Got a 2nd Tula this way).
But I gotta concur: For a new builder, Ak-Builder has some excellent kits. Most are already headspaced and fitted; indeed, it'll resolve a lot of "issues" that you could potentially have later on with a barreless kit. Although, if you're not already invested in building tools, it might be more economical just to convert a Saiga. (Assuming that supplies are replenished... you might have to wait out the supply drought).
Sigh. Like you, I jumped into the Ak-game late... It makes me sick to my stomach to hear stories about $90 Romy-G Kits. -Kinda like $200 Mak-90s back in the day.
Assuming that you're a new builder, of course. (Kind of pretentious of me to assume that you're like me). Although, you ARE asking where the deals are at right now.... so it's a logical assumption.
