trying to fund a new excavator wondering.

[cosworth34677]

so i been wanting a metal r/c excavator for a while. i could make one at work but the part that i kind of dreading is the track frames and turn table... in fact i hate that part..... anyway i was just wondering how much i could get for a used hydraulic bruder cat excavtor? just trying to get a price range to ask for, not really looking to sell right now but was wondering. because i would want enough to at lease get the new one going like the valves and pump stuff like that.

sorry if this is in the wrong section
