new to me sportsman

Hello all and thank you for all the useful information I sponged while lurking.
I am looking to get my first ATV, it’s needed since we moved out to the sticks and got more land. The ATV I would like will be a work horse here in Wisconsin, plowing, hauling and whatever else I need it for. It will be rare to take it on the trails. I have what I think is a good deal on a 2001 500 Sportsman with 1800 miles, push button 4 wheel drive, automatic. No winch or plow, but it’s in really nice shape for $2995 with very little wear showing. Could this be the good deal I think it is? Will it do the work I need it too?
I also have my eye on a 700 and an 800 that come with all the bells and whistles (no plows again but they do have 2500 winches). These machines have identical options and mileage is 1025 and 1182. With both ATV’s being virtually the same including both are 2006 besides the size difference why would they both be priced at $4995? I didn’t want to spend that much on my first machine but I may have to jump in.
Any suggestions and comments would help.
Thanks again, I will wait for your wisdom.
