I was asking around recently about the pro's and con's of the Mini 30 because I'm a big Mini 14 fan. The only negative issue I consistently heard is that many of them don't like Russian ammo.
BTW, $400. is an excellent deal.
“If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.” ― Samuel Adams
