fair price for an RCA 721TCS floor model?

[bmcgarth13]

Hey guys,
I have the opportunity to buy an RCA 721TCS, and I was just wondering what you think a fair price would be. it is about two and a half hours from my house. the gentleman says it was restored some years back, but obviously I would have it checked again. has all knobs, has the original back, has scratches but grille work is in excellent condition, and could be refinished well. are these sets super rare? what do you think its current value would be in AS- IS condition?

thanks a lot
Bryan
