richms:Issue I have on my cheap ryobi is the fence is a hard to adjust and get perfectly square to the table piece of crap. And the blade tilt is horrible to use compared to the better saws. Basically I finally got it to 90degrees and have not changed it since because its so damn hard with it moving slightly as you tighten the adjustment.
I've found this to be true with most cheap saws (table, compound etc, anything with an adjustable component) and it's a real curse!
