You really can't go wrong with either quad. The BF750 leans a little more towards the sportier utility side and the SP800 leans a little more towards the work utility side. But they are not that far apart. Polaris does offer the most dealer accessories more than any other manufacture. But you can get aftermarket accessories for any quad these days. If you do decide to get the BF750, I might suggest to replace the lozer stock tires with wider more aggressive tires. I put 27" mudlites on mine for regular riding and they are pretty good in the mud. They really eliminate the majority of the tippy-ness. I have ordered 3" lug vampires for my orginal rims so I can do heavy mudding. But, bottom line is ether way you go, you will be happy. Go test ride both and then you can get a better feel of what you are looking at. Good luck and let us know what you get.

 

my .02
get a bf or grizz

Both are good machines. Test ride both of them and then make you decision.
