I would think you'd be looking at something from the Kubota B series. There are many, many used and new options -- it's a very diverse series of tractors. In new, the B2320 is a really good value and can be had for not much more than a BX (there are some incentives running right now). There are used B2320s available too.
Give these guys an idea of your budget -- they may be able to suggest some specific models from the used offerings.
