I am all for that Formula!! I also found a few here and I am supose to go look at one Monday up boston way and he will take me for a sea trial.
I had seen this one before and put on the back burner, but then Therm brought it back up so I called the guy, He says all is solid and runs great!
I guess we will see on Monday? But I have to still sell mine :'(
