you can also take one of your 7.25's and throw a 8.25 blade on it wink. A couple of licks with a grinder might be required to enlarge the casing/base, but you'll save some $$ and put one of your 7.25's back to work.
FYI, Makita uses the same motor for their 7.25's and 8.25's and the 10.25 BigFoot is nothing more than a 7.25 wormdrive with an aftermarket casing and base...lol

here's my Hitachi fitted with a 8.25 blade, full 3" cut grin
