I just bought this Samsung Blue-Ray player that has an integrated HD Cable tuner. I already has a Cablecom Digicard (100 CHF one-time fee) in my TV, but didn't have the ability to record. I think this Samsung box is awesome for the price.

Pluses:
+ Don't have to rent a box from Cablecom

+ Razor thin
+ HD Cable tuner
+ PVR can record to external USB drive
+ BlueRay and DVD player
+ HD and 3D "upscaling"
+ LAN/WiFi media player (ie: can connect to your PC via LAN or WiFi and play downloaded media from there)
+ Automatic software upgrades via LAN connection
Minuses:
-Can't unlock DVD player for "region-free"
-Only one USB connector, and it's on the FRONT of the box
-PVR menu is not too user-friendly
-Recorded media from TV is DRM-encrypted, so you can't transfer it to any other devices like your PC
-Ony one cable tuner (DVB-C) so you can't record and watch a different channel at the same time.
All-in-all, it's a great box for a great price. If you just want a HD DVB-C tuner, prices start at 180 CHF or so. But with this, you get a DVD/Blue-Ray player included, with some 3D and HD upscaling. I don't have any BlueRay discs (and don't plan to buy any) but still have alot of DVD's, so at least I can use it for that. I also have a SAT-TV tuner, I would have liked to have a combo SAT/Cable tuner in one box, but there's not many options for that. Guess you can't have it all. But I'm pretty happy with this.
