DIY IR receiver - finding parts & advice.

[Justin <justin@xxxxxxx>]

Just before Christmas a purchased some Xantech bits from the States, one of
the 
items, a "Hidden Link" IR receiver, has died :(
A replacement is most likley out of the question due to shipping costs so I
thought I would look around for some homebrew solution I could put in the
Xantech enclosure.

I was thinking of using this circuit:

Anyone using that circuit? Is there something better I could/should
use?
I don't know where to get a GP1U52X (tried Maplin). Any pointers or
equivelents?
This would be wired back to a Xantech block so I guess would need to get
convert the 12V input to 5V but I'm not sure how to do that!

Any advice appreciated.

Cheers,
Justin.
