Good blade for Hi-Tech 6" trim saw

I've had a 6" project saw sitting in my shed for a decade and an MK 303 blade for it sitting on a shelf for probably 5 years. Just re-wired the motor, cleaned it up and did a few test cuts last week and the MK 303 goes through agate slabs like butter. Cut and trimmed some smaller agates ~ 1 to 2" and it sliced them nicely, thin kerf and clean cuts. Too soon to guess on durability but i've run a 10" MK 303 on my 10" saw going on 8 years now and it seems good as it ever was (i don't cut a ton though, probably a couple hundred cuts total on that one). No idea on price though i can't find them listed anywhere now when i search for them ...
