I wouldn't buy a bit set, for any price. What I do is buy a cheap bit off of ebay when I want a different type of bit. Then if the bit does what I want, I will buy a decent bit of the same type. This has worked out well for me.
I ordered the Masterforce 2 1/2hp plunge and fixed base kit from Menards. Hopefully a good choice, it was hard to find reviews on it but one poster on this forum said they liked it.A couple of different straight cutters, some round overs and a couple of top bearing bits to help with templates will get you started.
The big question here is, what router are you getting?
