The most bang-for-buck you're gonna get is most likely going to be the LS G3038 HST. I think there is also a TYM model that might be close, but I've been keeping an eye on that forum, and they seem to have reliability issues. From experience, I can tell you that the LS tractors are very well built and very reliable.
Keep in mind the generally accepted mantra here on the forum: whatever size tractor you think you want, consider jumping up to the next size because tractors shrink very quickly after you begin using them.
I think you will find most of the problems with TYM tractors are the smaller 2 series, my 353 appears to have the same engine and HST as the LS 3038.
