I've been happy with my
Bosch 1617EVSPK
. It is my first router, but I haven't had any functional frustrations with it, and it seems nicely made, so that makes it better than many tools I have purchased.

I've used it a LOT for many different projects -- much more than I expected when I bought it -- so it is nice to have a router that I like using (and quality bits, too).
I haven't tried the Bosch circle cut jig, but the
Jasper 200J jig works great with the 1617. I use the
Whiteside RU4700 bit
, which I like because it is a 1/4" bit with a 1/2" shank (so I don't have to change the collet when changing bits). I've never had to cut through anything deeper than 1", but the short 1" cutting length seems like the only potential downside to the RU4700.
Routers make a huge amount of dust. So for dust collection, I added a
dust collection kit, with a
Dust Deputy cyclone that I mounted to an old broken shop vac, and a
powerful and relatively quiet shop vac (cheaper at local stores) that is automatically switched on when I turn on the router via a
Craftsman AutoSwitch
. The Dust Deputy makes a HUGE difference in how long the filter lasts in the vacuum. I highly recommend some kind of cyclone, even if you are just sucking up sawdust from the floor with your shop vac.
I was rounding over the edges on a project today (a pair of AutoTuba subs), so I snapped a pic of my router and dust collection setup:
