Opinions on Meade 12.5" F4.8 Dob

I'm considering this scope off Astromart, for sale by someone within easy
driving distance. He's asking $750, which seems a little high for a scope
that sells on Astronomics for $845 + $79 in shipping. I'll save some bucks
on the price and not have to pay shipping, so it's a savings nonetheless.
Scope is allegedly 8 months old.

Are the mirrors in the Meade 12.5" generally pretty good? I'm sure that the
mount will need some TLC and eventually I might build/buy a truss structure
for it, but I've learned how to doctor the cheap structures to work
acceptably well.

I've also considered the GS 12" F5 which is "pretty close" in price. What
say you? Should I expect the Meade mirror to be better than/same as the GS?
