Well as of today the prices went back down to "normal" for all the gas engines in Saito line-up. Horizon has the FG-21 for $449.99 again. It may have been a pricing error which I'm thankful for - I'm back in the game for considering one again
Jim, I did check out your link and it's interesting that the carb for this engine is "discontinued". Hopefully the new one I purchase has the latest carb, if that is what's going on here.
