They are all good routers; it is really a matter of personal choice. Which
feels better in your hands; that sort of stuff.

The EVS isn't really necessary unless you will be putting it in a table and
using large bits.

I have the 1617 and the 1618 D handle. I love the switch in the handle of
the 1618 for certain jobs; though the 1617 is a little more intimate
feeling.
I bought my 1618 refurbished for about $160. You might want to do a search
on that. (I also bought my 1617EVS on Ebay for $120, but got really lucky.)
