That is basically my experience with them as well. I've assembled or performed significant maintenance on every printer model they've put out, except maybe the replicator 1, and I've never been impressed.

I've also had the pleasure of looking at disassembled Stratasys machines, and the design and workmanship are pretty impressive.
