Bosch Table saw. Maybe a Kreg router table. Those things are amazing.
A nice band saw for cutting rock wool with.
This could be a lot of fun.
If it's just for music. I suggest you build a nice pair of JL Audio 8w7s for the bottom driver and mod a pair of Primus towers. You can get them for 100 bucks and with mods(and all the nice tools you get.)
Make them into amazing speakers. Wmax has a post of them somewhere around here.
