I've had a Desktop for a few couple years and love it, I'm looking for something much larger now, was previously planning for a PRS Alpha but I just found this thing on craigslist and it has me tempted.

I'm meeting with the seller to ask more questions to make a better comparison, have any questions or concerns I should bring up? Foremost in my mind at least is the zeroing system, I love the aluminium plate too much to switch to anything else.
