Looking for info on Barudan BEVT z1501CB II!

Does anyone have experience with this machine? Im looking at buying one used for around 7750 with a TON of extras. It has a single owner and allegedly has been very well maintained. What should I look out for? what are general opinions of this machine?

And some technical questions I have:
Whats the largest hoop size available for this machine? The embroidery area says 330/500 but the largest hoop i can find researching is decently smaller than that.

Is there a table top for the machine and is there a border frame available to take advantage of the full embroidery area?

Are there any good video references to help me learn how to use it other than downloading a manual?

Im new to commercial machines and my only trepidation of buying a slightly older machine is is having a hard time finding trouble shooting help online that is readily available for newer machines. BUT i know Barudan is really solid and everything id be getting is an insanely good deal if everything works as it should
