I know some will jump on me for this but do look outside of ebay, also. Ebay has had issues with crooks with tractors. Do not buy unless you can put your hand on the tractor and deal direct. Same for used tractor with individual. Too many are stolen and turned real quick. Especially this time of the year.
There are some commercial, dealer type large search sites out there, do at least check them for comparison.
That being said I have a B2710 Kubota that has been good to me, would do probably what you want but I would suggest the "L" series over it due to the frame size as has been noted. Service and parts will be what makes or kills you pleasure with the tractor, all need service and repairs and you want a brand you can get both for. You may wish to spend a few hours reading on this site about problems people experience with a brand before you buy. In the size range you are looking at John Deere, New Holland/Case do not make their own and therefore support if they have them is not the same long term. Kubota and I think Kioti make all theirs, not sure on Kioti.
I would not want a Chinese tractor regardless the label on it. Just read about getting parts, again even here. You do not want a "grey" market tractor. They are brands sold here but those models are not built for the US market and not supported.
Yes there are those who get good service from their grey market tractor or Chinese tractor but when mine needs a part I do not want to wonder will I ever get it.
