There is a dealer here in Baton Rouge, LA selling a 4-5 year old G1900 with 850 hrs for $5000. The salesman and I both agreed that was way too high, and he told me to just make them an offer. 5 grand is pretty close to a brand new TG1860 with ZERO hours and a warranty, so I never did make them that offer. He also quoted me $8500.00 for a new one. (although thay are being discontinued)
Anyway, hope this helps.
