5L Manual Lift Oil/Water Bath

Hey forum, I got an RE-501 5L rotovap for Christmas last year and I can’t use the water bath in my house because my house can’t handle it. It’s in great condition. 5L Capacity. It’s been in my attic I’ll clean it off before I send it out. I’m hoping for 500$ because I don’t know how much the fair asking price would be. Willing to negotiate. I’m also interested in trading. One thing I’ll trade for is a 6×6 Hemispherical Lid or if anyone has any pre-configured 6×6 cls lids they’re willing to trade I’ll take that as well.
