I bought mine new, traded in a cat 302.5 for it, cat cost me 16K and I spent another 8K to get the u15 with thumb, three buckets and a gently used hammer included.
Business was slow at the time and the salesman bent over backwards to make the sale. Plus the u17 version just came out and mine was the last 15 on the lot
The thumb is an amulet version and is very good quality but one gripe is it doesn't mesh properly with all the buckets, not a deal breaker though
Plus they had to add the quick coupler system for hooking up the hammer...
I then made 6K on the first 20 hours of use with it on a job where a bigger machine wouldn't fit
