Oh, absolutely. Even on just that last issue of cost, buying my own cable-modem paid for itself long ago, compared to the "rental" cost from my ISP.
On that note, it's better to buy a router separately from the modem. All-in-one devices are harder to diagnose and you can't reuse the router with a different connection type.
