I've had a Belkin and a NetGear - never been able to pick between them, but I'm sure someone has a theory why one is better than the other.
Apparently the BT model has better range? no idea, but it's worth remembering that where you place these things can have a huge impact. To keep mine near the model it sits under the TV next to the DVD, Video, and WII which is fine when I connect in the room, when I move upstairs the connection keeps dropping out until I move the router out onto the floor in front of the TV stand, then I get almost the same quality of connection at the back of the house as I do right next to the router.
