There will be lots out there to choose from, but which ever one you get, be sure to buy a speed control. The bits are very hard to control without it.
I got mine from HF, it's listed for a router. Very handy. I even use it on my drill to slow it down for larger drills.
FWIW, I got my grinder from HF too. If you cheap out like me, be sure to buy the extended warranty. This is my second one since the switch only lasted 3 starts on the first and then " no clickie."

It may be ugly, but it sure is slow.
