What is a fair price for a used RT-PRO?

What would you expect to pay for a RT-PRO in near new condition? (marker only w/ no upgrades)

I'm looking at one on ebay, but I think the price is a little steep. Actually the price may not be bad, it's just that I don't really desire any of the other items included in the auction. The tank is a 3000psi and I'd like a 4500psi. and I don't really care for the loader or the mask.

search on the B/S/T forums on this site for one. you can find some fairly priced
