Since TWC is becoming part of the Spectrum network, I think your best bet at this time is the Motorola/Arris SB6183 DOCSIS 3.0 Cable Modem, which is exactly what I'm using now.

Other than ordering a new battery from Dell, this one seems the best choice: Model: NM-RU586-9 SKU: 1342203

Usually, sale prices on items run from 00:00 on Sundays until 23:59:59 the following Saturday. If your purchase isn't completed by the cutoff, the price reverts to the pre-sale price - even if the item is in your cart but not purchased.
If you're still interested in the HP 8620, it's back on sale now - at the current sale price, it's a great deal - I have one, and I love it!

I guess a lot depends on the make and model of your VHS player - if Logitech has that model in their database, the remote will control the player (after the remote has been programmed with the commands for that player). On the other hand, the make and model of your AV tuner or TV is also important, because all ANY 'universal' remote does is combine the operating signals for several makes and models of devices into one unit, so you don't have to juggle two, three, or five remotes just to watch what you want to watch. The device being controlled doesn't care what brand remote you use, as long as it recognizes and can execute the commands it gets. I've used several generations of Logitech remotes over the years, and they've all worked great once they were programmed. Hope this helps.
