I have been using this 8 relay USB remote board from Poland (ebay seller ojtush), it is quite a bit cheaper and for my purpose, better.

I also have the Velleman 8055, however I much prefer the Polish board as the relay states do not change until you command it to - so very stable, but the 8055 will reset the outputs when you reconnect if you reboot or loose USB connectivity for any reason.
