Right now I'm just looking at something for 2x4, 2x6, and 2x10 cuts for framing. I can always switch back to the abrasive blade for cutting my vinyl siding and J channels.
For anything over 2x4, in a miter cut, you will need a sliding compound miter, a radial arm, or a table saw.
Over the winter I'll be looking at buying a table saw. I want to buy some decent plywood and rip it into 6 inch wide strips to make some plank flooring.
You'd be surprised how much you can do with a simple contractor's table saw... First thing to build with it would be a set of horses to sit it on, a sub-frame to sit it in, a side table top, and a catch table top... The all you need is a pipe clamp to make a decent fence with and you're all in...
The only thing I wish I'd have done was to go into a higher end contractor model - I can't dado well with the one I have... Not enough throat, and not enough power.
