I'm looking for a router.. preferable a wireless router with unlimited
nat entries or at least 50 spaces for nat entries.  I have alot of
servers setup at home and need acccess on different ports.  My old dsl
modem/router had no problem. I think that I had about 60 in there, but
most routers today are limited to about 20 slots

Cisco is the leading business router provider.

I doubt that a company like Linksys will offer what you are looking for.

Buy a linux-based router.. if the original firmware doesnt have the
features you need, use openwrt (www.openwrt.org).. Check the hardware
compatibility list and be sure of buying a compatible router...
