Help setting up multiple routers in home.

first off, i have a netgear rp114 right behind my cable modem with a
few nodes hanging off of that. i want to add a wireless router off of
the netgear and have a few more nodes off of the wireless router
(wireless and direct). the problem is, i can't find a wireless router
that will let me have different subnets, which is what i want. i could
probably set any of them up as a gateway and use the same subnet,
but...

i've considered standard, wireless router products like netgear wgr614
and the linksys wrt54g. maybe i need a wireless vpn router, which
usually will cost me $350+...

thanks to all who reply...
