Take it from someone who has and uses 7 different routers:
Dont worry about the base taking templates. On cheap routers they are never reliably concentric to the bit and you will be better off with a bit with the bearing built in.
Don't buy anything with a digital depth gauge. for the type of use you're considering, you need to test cut a scrap piece and measure to fine tune your depth.
Consider a laminate trimmer if you don't have to make any big rabbets or dados (i.e. 3/4" wide grooves in wood). If you're just routing mdf and rounding over a laminate trimmer with a large base will do you just as well.
remember, ok to go cheap on the router but don't go below Bosch/amana/cmt quality level on the bits, it will not pay off. be careful, routers are dangerous. any questions, please reply or PM - happy to help.
