I agree with what's been posted so far - get a nice router (at least
$100, Bosch, Porter-Cable, Dewalt, etc) with a 1/2" collet. Pat
Warner's site is helpful, and I'd also recommend looking at general
woodworking books, or books specific to router use.
One useful accessory to think about is an offset sub-base - I think
these are recommended and maybe even sold at Pat Warner's site. I have
one from Rockler that was designed for use as an edge guide, which I've
found very handy.
Have fun routing,
