JeffreyG,
Welcome to TBN! I'm usually with the crowd that opts for the biggest tractor you can afford. (I've got a B2910 on 2/3 acre, so I follow my own advice. /forums/images/graemlins/crazy.gif)
Anyway, I think you need to look at a bit more than just the price of the various tractors you're looking at. Try to assess what their value is to you. Keep in mind that quality tractors don't generally depreciate as rapidly as cars, so they retain their dollar value much longer. Usually, their greatest depreciation is within the first couple years, and compared to autos, the percentage is much less.
Personally, I think spending the money on a "departent store" tractor is a waste. If you need a short term solution, it's O.K., but they generally won't hold up to long-term or heavy use.
Although I would "love" to see you get a BX2200 or even bigger, I think the BX1500 is a quite capable tractor IF you understand it's limits. From your posts, it sounds like you're doing a lot of work by hand that your tractor could help you with.
IF you can swing the BX1500, I would seriously consider pricing one with the mower, loader and possibly a small rear 3 pt. snowblower. Finance rates are still low, so if you can take advantage of them, that can sometimes soften the sticker shock.
If you have to wait for the snowblower, then wait. From what you describe, I definitely would get the loader. If you don't, then everytime you reach for your wheel-barrow, you're going to look at your tractor just sitting there, and kick yourself for not getting the loader. And they are usually the best value at the time you buy your tractor.
Now, if you can swing a few more $$$ a month, then look at larger tractors. If you are really stretching (but do-able) to get the BX1500, then I'd advise you to get that model. (I would also check the other name brands for comparison, but I personally favor Kubota.) Consult your local dealers and see what they recommend. If you "hit it off" with one dealer better than another, that might help with your decision.
I was in a similar situation over 3 years ago and I bought what I felt was the best value. I'm still happy with my purchase.
Good Luck,
~Rick
