WTB: Fully Assembled 3D Printer

I've been following the 3D printer world for quite a while, and it's time to jump in. While I am an engineer, I finally have to admit to myself that don't have the time to build a printer myself (3 kids, job, ...), and I'd rather spend my time designing and printing things than in debugging the printer, so I need to buy something that I can buy and use with fairly little fiddling around. But I can't buy a $10K+ commercial printer.

The latest models of all of the 3D printers all claim to be reliable, so I can't really tell - are any of the home 3D printers reasonably close to "plug and play"? The most reliable sounding printers are the Up! and the MakerBot, but there are quite a few newer RepRap's that also look interesting (and a larger build area is certainly appealing). Perhaps I should buy an assembled printer to start with, then build something like a Mendel?

What do you guys suggest?

I have been printing with the first of the prusas that I assembled for sale for about 9 months with no problem. It has a number of features that aid reliability:

All metal hotend: no popping nozzles out of ptfe when the temp gets a bit high. this is a common failure mode for many.
lm8uu linear bearings: these keep on trucking. PLA bushings would have worn out or gone sloppy by now.
glass build platform: remains flat. very durable.
stainless frame and rods.

The full 200x200 print area is usable:

I will sell you a fully assembled reprap huxley for $620 flat.
Interested?
