Steven, I have the same sander, and it is fantastic, you will definitely want to mount your router in a table. I have mine in a table with an 1/8" round over bit in it all the time. I have a spindle sander, that I do not use much. As far as a belt/disc sander, I use it all the time. In my opinion if you can afford the 9" Disc/ 6" by 48" belt get the bigger one, I have had a sears for a couple of years now that works well for me, it has a built in dust collection, just hook up your shop vac. Have fun, I love tools.
