I was in the market for a 3D printer a while back, but I was really put off by how low quality, amateur-esque the entry-level 3D printers were (Reprap and co) at the < $1000 price mark; while on the other hand, how freakishly expensive the professional 3D printers were ($15,000+). I was surprised at the lack of options in the middle. Replicator 2 seems to be a step in the right direction, but it's not quite there yet IMHO.

Does anyone have any recommendations in the $5k range? A larger chamber size is an absolute must.
