Well Folks, I BOUGHT IT!! I read as many reviews as I could find on line, and the ONLY reported problem was the Blade Clamp screws rounding out. MINE...rounded out after only 4 blade changes!...BUT, they are a standard screw, and I bought 20 today for just ?1.50 UK (about $2 US) from a local hardware shop. The saw itself is GREAT! There's NO blade deflection, minimal vibration, and constant stroke speed even in wood of 20mm thickness (3/4 inch), and the motor hardly gets warm even after an hour of quite intensive sawing.
Am I happy with the saw?...YOU BET!
Now it's a case of Practice, Practice, & more Practice...but I'm enjoying every moment of it!
