Have any size/weight/portability restrictions?

It looks like the Rigid R4560 is the current incarnation of the table saw I have.

It's hard to go wrong with craigslist if you live in a decently dense area. Worst case, you can always sell it for around what you paid for it.

If you're going to be cutting large pieces of wood, having a heavy saw will give you more stability. You're also going to need something to help with indeed and out feed if you're going to try to cut something like a 2x4.

As an alternative, or potentially a companion, consider a track saw and sawhorses or even a circular saw with something like this. I break down large pieces of wood this way now and then being them to my table saw.
