It's pretty much because wireless is becoming the standard, and doesn't cost all that much to put in. Thus most wired only routers are thus either older, less common, or are actually pretty serious VPN endpoint, IPsec handling, etc. home office jobbies. That being said, I've never run into a wireless router where you couldn't turn off the wireless component, so you would probably be safe to grab the cheapest one that doesn't have horrible reviews and then just turn off the wireless component(if you are feeling really jumpy, or you somehow get one where it cannot be disabled in software, a suprising number of access points actually just have wireless PC cards being run in AP mde. Pop that sucker out and you won't have wireless(and you will have a little something for ebay)).
