Have you considered getting a shaper, instead of a router? Then you
can have a nice beefy cast iron table and an induction motor. Mine's
only 3/4 HP, but it can cut through oak and maple like butter with my
3" raised panel cutter. A friend of mine borrowed the cutter to do
some panels with his 3HP Porter Cable router. He told me it took him
five passes to eat through the wood without completely bogging down the
motor. Like I said, my shaper does it in a single pass without
flinching, though I usually do one last 1/32" finishing pass just for
looks. Since it's an induction motor, variable speed isn't an option,
but it spins at about half the speed of a router (~10k rpms I think),
so it never burns anything. Heavy duty fence, heavy duty knobs to
raise and lower the spindle and to lock it in place, built in dust
collection port, ability to wire to 110V or 220V, and built like a
brick outhouse - what's not to love?. I got it 5 years ago for around
$400, and I've never used my router since for anything but hand work.
