Buying a second cable modem instead of renting

[acperience7]

I called my ISP a few days ago, and asked them how much it would be to rent a second modem. I was shocked to find out they want to charge full subscription price (which actually makes sense). I checked newegg for a modem, and I was thinking of buying one and hooking it up to my cable, so I wouldn't have to pay the extra subscription fee. Is that illegal, or have a just found a good loop-hole?

And how do you plan on using this second modem?

I mean in theory, you wouldn't be able to use it without registering it's MAC address to your ISP, then they would charge you a second subscription fee anyway.

I was just going to use it for my PS3. I didn't want to get a router and have to muck around with all that port access stuff.

It's the easiest and cheapest way, getting a router. Plus, as long as it's got UPnP (Universal Plug'n'Play), it should configure ports automagically, or mine does anyway.
