G'day,
I have various Ryobi power tools including a scroll saw and plane. I have had Makita and dewalt amongst other brands and have found if treated right Ryobi measure up perfectly. The one thing I have found with any saw, especially compound saws is that the bigger wattage motor the better the cut. I believe this because the blade spins with higher torque and therefore doesn�t 'bog' down as easily.
as to which one if you were like me and used it every few days for minor to major jobs I would spent the extra, but if its a 'I need one for this job' the cheaper one would probably perform fine assuming its got enough capacity
Anyway there just my thoughts. Ow and as to blade, ive got away with the standard coarse one fine in my GMC accept when cutting melamine.
Regards jay
