I've very pleased with it. It did the job I bought it for. In terms of accuracy, I usually print with a 0.3 Nozzle at .1 or .15 layer height. Most of my work is for maps, so I don't go very tall. I can fill up the bed, and with proper prep, I can print 16" x 20" 1" tall maps without warping. I found BuildTak to be my best bed. PLA, 205°, 50mm speed, 55c bed. Prints that take me 11 days aren't uncommon, but the top layer looks like silk.
I'm not a huge fan of the volcano, I've had to rebuild the head often. Not a huge fan of the titan extruder, either.
Yes, I'd buy again. If a big job comes down the pike and I need another machine, I'd buy the V3. They changed a lot of things that needed changing.
The machine itself is a sturdy beast, and the best FDM printer in terms of print accuracy. I use my Phenom for stuff that has to be perfect (topo maps, braille...)
