Hey Burk, that's pretty much what I paid for a very similar setup in Central Michigan.
I've got a pretty rough 10 acres to play on, well, 5 is ours and the other we have permission to 'tractor' on. I've got 23 hours on my
B7510 right now, and couldn't be happier with it's performance. Plenty of power, extremely manuverable, easy to operate, sips diesel...I've been quite pleased with how easily it gets things done, and how much fun it can be doing said things.
Used it last weekend to move a 14x14' screened in room that was sitting on a treated 2x8 14x20' deck. Lifted a corner (and was very shocked it didn't grunt at all), put some blocking under that, and moved around the structure doing the same, then threw some planks down there, some Sched. 40 PVC and away it went.
Our terrain is pretty rough, and I'm glad that I went up a notch from the BX I was originally considering. Would've been bottoming out, no doubt about it.
So, in closing, I'd say (look at my picture first, then),
B7510 all you can
B7510.
