One of GC's listings is around $140. http://www.guitarcenter.com/Used/Fender/Rumble-60-60W-1x12-Bass-Combo-Amp-112841127.gc?cntry=us&source=4WWRWXGP&gclid=CNOdqr_f69ECFY-6wAodEhIFXg&kwid=productads-adid^66736785762-device^c-plaid^172971158922-sku^112841127@ADL4GC-adType^PLA

Understood- I waste money on amps*, too.

justinguitar.com is the answer
It also depends on the vintage. There have been at least 3 series of Rumbles if I remember right. Some of the earlier versions were Ok and don't fetch much on the used market. The newer versions (Series 3) which were introduced around 2014 are far more desirable on the used and new market and fetch better prices.
^ A lot of truth to that. The newer Rumbles are significantly better and should retain a bit for value if in good condition.

I have one of the old first generation Rumble 60s and I'd probably ask $100 and be willing to let it go for $80 if I were posting it on Craigslist. GC would probably offer me $10 for it.
