I picked up the regular edition for $25 at Fry's a couple of weeks ago. Decent game, but there are very few ranked servers, and the server browser is a bit shit. But the last patch (I think) added VOIP, so maybe more people will be playing it.
Hmmm, I've been playing exclusively on ranked servers for the last couple of weeks and haven't had any problems finding matches. It really is a shame this hasn't done better commercially because it's a heckuva lot of fun.
