I have the same saw, the fence is kinda crappy, I gave up on the ruler and measure to the blade with a tape measure because Im anal about it and then use a bar clamp on the back end of the fence so it doesn't slip. Otherwise it works pretty good on small stuff, but on bigger stuff I usually use the circular and a piece of wood as a guide.
I have a lot of Craftsman stuff...I like to break stuff.
I have had good luck with their power tools too, but they usually only have a year warranty. I have a bunch of C3 cordless tools (couple drills, trim saw, jig saw, sawzall and a couple others) and they work well.
I got my card when I was like 18 or 19 or so and I'm 22 now. I just got a 15000 car loan in November with a good interest rate and didnt need a cosigner.
I ended buying lots of crap off the internet with my card and I paid it off when the bill came. The only time I didn't pay in full each month was during the introductory no interest period and even then it wasn't fpr very long. I also got some home audio equipment at a local place which gave me a pretty high limit which i paid off pretty quickly.
I had a check about a year ago and my score was at 736 (that was before I had any loans).
In short don't pay interest and your score will go way up and so will your limit.
