I bought this about 3 weeks ago to split the signal between my PS3 and Wii. However, I've just replaced my amp with one that has in-built component switching so I no longer need it.

By all accounts, this is one of the best component splitters for it's price and is fully compatible with Sky HD and all consoles. The best feature is that it auto switches so there's no need for an extra remote or to go fidddling behind your kit to switch input!
I'm looking to get back what I paid which includes the Component controller and its' power supply for £35 including delivery. Payment via cash/checque/BT.
Any questions or if you would like any photos, let me know.
