CTC printer but, which one to purchase?

[curious aardvark]

personally I wouldn't get a ctc.
They do seem to have a lot of build quality issues.
Probably why they're so cheap.

So if you would list the three models, I can take a look and see which is the least worse :-)

Problem is nobody else seems to be making the classic makerbot dual clone anymore. The rest just seem to make the pro version, which is about twice the cost.
