recommendation for RF remote

[fuzzweed]

Hi, can anyone recommend a USB RF remote? Needs to be RF because the PC is in a cupboard. Most importantly it needs to wake from standby with the remote.
I've previously used an Emprex one which was perfect functionally, but the remote kept breaking. I've had (and broken) 2, and I'd get another but they were hard to come by last time I checked Ebay.
Most recently been using an X10 remote, which occasionally wakes from standby, but is too hit and miss to be reliable and useful.
UK availability and modest price also important....
