Logitech Harmony Adapter For PS3 - Where To Buy?

Hi.

I was kindly gifted a (barely) used PS3 just before xmas, and I'd like to integrate it with my AV system.

I use a Harmony 555 remote. I need the Logitech Harmony Adapter For PlayStation 3 for that to work, but at £40 STG, a new one is well out of my budget (and ridiculously overpriced, particularly for a last-gen accessory), and I'm not sure where to find a used one.

I'm also looking for a Sony Play TV Tuner, but they seem a bit easier to find used.

So have any of you guys got any suggestions?


Thanks for any replies,

Mark
