For snow and light grading around the house I'd go with the KK from TSC.
Well built, and the price is right.
Check around local listings too, I have seen used, but in good shape, RGBs go as little as $150.
Also, opinions may differ, but I would also look at a 60" RGB for the BX.
I used an RGB for snow clearing for better than 20 years. They work, and work better once you get accustomed to them. Front blades with power lift and power angle are very nice, and also very pricey.
The RGB is probably the cheapest, by far, method for snow removal.
I say think about a 60" RGB due to my experience using a 72" on my Ford 1210 for 15 years. For smaller snowfalls, the 72" made quick work of the driveway. For heavier snows, deeper and/or wetter, you start to push a lot of weight in front of that 72" blade. At a certain point your tires start spinning then you have to reposition, take a chunk of that mound, and manuever it off to the side.
When I got the BX I decided to fix it, I cut the 72" down to 60".
I would rather have to take another swipe , but be able to push it the entire distance, than take a wider swipe, but risk spinning to a stop.
I think the BX has the power, I just don't think it has the weight going for it.
Once I cut down the blade to 60", I had some ground levelling to do, that is when I noticed the difference in cutting ability in dirt, the smaller blade length took less effort to grade off an inch or two of soil.
Sizing the blade is not an exact art.
The slope of your driveway, the material it's made of (paved or gravel) as well as your region and types of snowfall will dictate what blade is best.
If you get a lot of light and fluffly snow, then maybe the 72" will be fine.
If you get thick wet heavy snows, filled with a lot of moisture, then the 60" may be the better choice.
