Go to a dealer and price out a new 2920 with the same options. We have the same exact setup and it's been an awesome machine, haven't had one problem except changing the hydraulic lines. Not bad for being 14 yrs old and it's still on the original battery (but starting to get weak). The backhoe is a 3pt mounted one and the new 2920 come with a subframe setup which is better.
That price doesn't sound too bad for a low hr machine but make your own judgements off a new one.
