Is the Adcom GTP-750 any good?

Hello all, I am new to the site and looking for a little assistance. I have come across a new GTP-750 from a trusted source for $550. This is my first pre, and while I don't have a lot of cash sitting around, I do not want to buy something I will regret. If anyone has any experience with this unit or any knowledge I would appreciate the advice.
Thanks, Matt

I will read your comments...
Thanks;
