Agreement with everything posted thus far - another option is a Mini ex either a new Chinese mini which for $4K you can get a 1 ton gas model and for $9K a 2 ton Diesel model.
Pros - are inexpensive, can do a decent amount of work, good for small projects, trenching, occasional homeowner use,
Cons
-Are slow if you have a lot of area to cover
- Arent very heavy so dont have a lot of digging force - but the 2 ton mini is close to what a small TLB will dig - 2300Lbs force. '
Or wait and look for a used one for your machine - probably expect 2/3s of new price so 6-7K.
