John,
Do you need the ground capabilities of a garden tractor, i.e. tilling, single moldboard plow, etc? If not, then get a JD X300 series. They can handle a snow blade, snow blower, and you can get a shovel for them (I wouldn't recommend that though). If you need ground engaging, then you have to move up to the X500 series, which are more expensive. I wouldn't mess with the D-series as they won't compare favorably with your 265.
