..Here's an old thread dealing with fence alignment..

..But how much are you wanting to spend and what type and how much use will it get? How portable do you want the saw?
..For some comparison reading you might like this for general info but take it with a grain of salt..

..I have a few different portables I use for different things..
..I wore one of these out (with no stand or dustbag) using it everyday for a couple years and it was fantastic as in lightweight and plenty of torque for cutting maple and oak..Used for complete kitchen installs. (I wouldn't recommend it for a beginner)

I will be buying another one and I believe this model number is correct 3400 and I paid $100 new threw the dealer (Bosch and Skil are owned by the same)
..For bigger jobs as in onsite custom cabinetry, this is my go to portable..Bosch 4000-07 jobsite table saw and I have the optioned side and rear feed slide outs which make this table saw as close to a full shop saw that is portable. This easily handles ripping full sheets of plywood also..
..The current model I believe is the 4100-9 with gravity stand. Here is a link to a review with a video on the gravity stand too..(this is model 4000-9)

There's Makita but they are not getting to good a review in the field since they sent their stuff to China to be built..
..Two other common industry standards are Rigid and Dewalt..
..Rigid is now a name to steer clear of as in no company support and any major repair shop of brand name tools will not deal with them anymore..(I recently replaced all my lifetime warrantied drills I had with them to other brands and am down to my 10" chopsaw as my only rigid tool left, because of the warranty repair issues) Home depot slowed what they sell of Rigid and didn't support the tools they sold..:thumbdwn:
..Dewalt..I've had several competitors who had to have the top name tools and I've watched them often lapse into down time with fence and other problems as there are a few common plastic wear parts on their table saws that often need replacing...
..Sawblades are also a key when using table saws...The blades I purchase are commonly in the range of $50-$80 each and not only do they last a long time, they cut well putting less strain on the motors for longer life of the tool itself. I see a lot of people buying the cheaper blades then watch them burning thru material and you can hear the bearings ring..(It's kinda like watching someone weld 1/4" steel while being setup to weld 1/8"..

)
..But I will let you in on a common saw they can't keep on the shelves right now..:shifty_ey...It's cheap and has some options if you don't need it to often..I haven't used it but see them being sold out often..
