Can't Say It's Worth the High Price
Was really excited when I got this printer earlier this year. Have had a few issues with it and Aleph Objects have been very terse in their responses to my support requests, and very reluctant to provide a remedy for things that were clearly their responsibility under warranty. Take a look at the company's employee reviews on Glassdoor and you might get some insight into why their customer service level is declining. Whatever the performance and quality of the printer, I'm now wishing I had not supported this company by buying their stuff.
The print quality and build quality are good, but for the price they charge for this thing, they should be between great and perfect. If the printer were sold for about 1/2 what it goes for, I might have rated the value a bit higher. Couldn't really recommend this as a good bang for your 3D-printing buck.
I would also recommend searching for 3mm filament options and compare the availability with that of 1.75mm filament offerings before choosing a Lulzbot printer. If you like having lots of options, the Taz 6's use of 3mm filament may not be ideal.
