Looking for bluetooth keyboard with trackball for HTPC

Can anyone help me with my search for a compact bluetooth keyboard with built-in trackball/trackpad that I can use with my HTPC?

All I've seen so far are infrared (don't wan't hassle of line-of-sight) and proprietory 2.4GHz (don't wan't another 2.4GHz device, already got Wi-Fi, Bluetooth and Sky sender) solutions.

I've seen some that are shipped with media centre PC's but don't think that I can buy these separately.

Any help will be greatly appreciated. Thanks.

Given up on the bluetooth idea and have ordered this one...

Getting it from Ceratech.co.uk though at £46 ex. vat instead of £69 ex. vat.

Has anyone got one already?? Seems ideal for an HTPC, great range and optical trackball, but hope it doesn't interfere with Wi-Fi and video sender.

yup - currently my favorite keyboard for MCE. Looks like ceratech have put their prices up - and how much from that keyboard place :o
