You'll get lots of advice here from the members on this topic...the question gets asked a lot! Nobody likes making the wrong decision.
But when you're making your choice, take Customer Service and quality control into consideration. If things go wrong, that's not the time to discover that the parts aren't available until Never.
Personally, I recently bought the Bosch 1617EVS specifically to mount in a new router table. I already had it's big brother, the 1619EVS plunge, but since I prefer hand held routing, for what I normally do, it's not going in the table, even though i think it's the only plunge that has a spring defeat built in (specifically for RT use).
BUT if after reading and hearing reviews about Bosch you decide the 1617 series will do just fine, please consider the 1617EVSPK...it comes with both a plunge and fixed base, for under your budget.
