Hi Group

I recently bought a SX-210. It plays great but a few pushbuttons 
(w/LED) didn't survive the trip too well. The plastic caps are smashed. 
Some LED don't illuminate anymore. My question, where can I find 
replacement for that kind of pushbuttons? I've searched for days on 
Google with about every keywords I could think of. There must be a 
supplier somewhere with that kind of switches, with different colour 
caps. I've even looked on eBay and found nothing. Maybe I am not 
looking in the right direction.

Thanx
