I've been debating buying a new saw to replace my 20+ year old Craftsman tablesaw. I did my research and picked out a few models I was interested in. But, I had a hard time spending money on a new saw when my old saw was working fine.
My saw is probably worth less than $100 on today's market. Small aluminum table, 13 Amp motor, direct drive, maximum 2.5" depth of cut, and a really bad fence. But, it has been very reliable and rugged despite a bad power switch and my abusing it dragging it out into the yard and whatnot. On the positive side it has an induction motor, left tilt arbor, is small enough to store, and light enough to move around the garage easily.
In any case, after replacing the power switch and a lot of debating, I sprung for a Mule Accusquare fence (Their smallest model 825). It cost me about $180, and is clearly worth more than the saw. But, it was still a third the cost of a new low end table saw.
It took me about 2-3 hours to remove the old fence, install the new one, and get everything tuned up. The fence arrived with a broken plastic "cursor", but Mule sent me TWO replacements free of charge.
I've been using the new accusquare fence about a month now, and I have to say I am very pleased with it. It's quick and easy to set, stay's aligned, and is accurate. I can actually set the fence using the built-in ruler instead of having to measure from the blade to fence for every cut. It's amazing how the simple addition of a new fence has transformed my little table saw.
So, I'll keep using my old Craftsman saw till the motor finally dies. Then I might spring for a new saw. On the other hand, a replacement motor is only $200... Hmm... :)
