I will argue with each and every soul that says an arm lifter is not necessary. I went for 8 years without one...used a block of wood. I splurged last year and got the Jim Dandy, mentioned above, and it is the single best purchase I have made. Yes, it is a top feeder, but every time you put the arm up you have to block it to keep it up while you feed the blade through the hole in the wood...at least if you are doing a fret work. Now I just push the arm up and it stays there. I can't understand why that is not part of the package. As for lights I have an old one from somewhere that has a big magnet base. It just sits way back on the saw's table and I can adjust it. Sorry no help about where it came from but it works great.
