I am a long time Solidoodle 3 user, with a heavily modded printer. And I must say that even though their quality control is pretty darn atrocious at Solidoodle from my anecdotal experience. I think they've got a very nice all-purpose design. There are things that are for sure wrong with it, but then again this is part of playing the early adopter buying game that we are in right now with 3d printers.
Not excusing there weaknesses in their design. But I think for what is available Solidoodle offers a great printer for the tinkerers, engineers, and more technical users out there. If you want a perfectly polished machine solidoodle seems to be a gamble so far.
All that being said I pulled the trigger quite impulsively on a Solidoodle Press because it's a Solidoodle 3 / 4 with a prettier cover, and auto bed leveling compensation.
It was a no brainer for me to drop $460 (that includes shipping) to get a pretty cover and auto bed leveling. Especially since I can turn around and sale my very nicely modded solidoodle 3 for $475. He wins because it's a standalone printing, beautiful calibrated, no risks solidoodle purchase-I have a buyer who is on the verge of pulling the trigger this thursday when he comes to see it in person--I win because I get prettier bones to mod again with minimal financial loss. I'm hoping, perhaps generously so, that after their multiple generations of design revisions we're finally getting close to a real polished consumer product in the solidoodle press as opposed to the mad scientist kit that was really what you bought when you got a SD2 or 3. As far as customer support from solidoodle... The key is to inspect the crap out of the machine as soon as it arrives, call them immediately with anything that seems unreasonably outside published specs. Than be prepared to be on your own, and work with the soliforum community. I have little to no confidence in there customer support. Even thought they have been very generous with me. I hear too many horror stories.
From what i can gather the press is a SD3,4 + bed level compensation probe, power switch, and glass bed. And I am pretty positive it's meant to take the place of the SD4 in their product lineup. They are simply selling off their stock of SD4's before they kick them out of the lineup. Honestly I think it's unwise for anyone to purchase an SD4 at this point.
They are obviously angling to be in more brick and mortar stores with the press. And the workbench, and workbench apprentice is their answer to competition from makerbot, ultimaker, and everyone else.
Anyhow, I'm excited to be in the early batch of Press owners, and I also think that like most technology I expect it to be obsolete in 6 months to a year. Just part of the tech world we live in.
