I'll chime in on the Replicator 2, since we have several of them and hundreds of print hours. For what they are, they're not bad. Leveling is a pain, no soluable support, prints of certain geometry can warp, large flat prints delaminate from the build platform, and the extruder can sometimes clog, or run out of material, or disassemble itself and crash into the print. But, we have not had any serious issues with the machines that we could not resolve rather easily (add more Kapton tape). Some of the printers squeak and make odd noises at times, but they keep on printing just fine. If you know what you're doing, you can probably achieve a 75%+ success rate with it. The quality can be surprisingly good at times, but it does not hold the tolerance of higher end machines. A 1" hole in a part could print as much as 40 thou small.

We've made plenty of neat little parts and a decent number of actual functional parts on it. For the price, we've been happy enough with them.

They are way faster than our old Dimension SST 768, in every way.
