Just get a high-end ($200+ class) wireless router, and disable the wireless. They don't really make SOHO wired routers any more, there's no market for them.
Edit: Look up SmallNetBuilder, they have "Router charts". Look for the "WAN to LAN throughput" numbers, and pick something with 200-300Mbit/sec or more. (For future FIOS speed expansion.)
that is wrong larry..
Ubiquiti EdgeRouters are basically enterprise class SOHO routers.
They also fit his price range, and can be hammered with torrents without a hickup.
However the OP is probably better off building a Pfsense/Smoothwall/IPCop box using a Dual Intel Nic Atom board + 2GB of SO-Dimm and a small SSD which should run him about 200 dollars.
The best thing of all, the software is free, and is easy to install via USB thumb drive.
And both these options will spank any Netgear / Asus consumer based routers.
However those 2 options are not easy to setup, and would require some research in how to set one up.
