There's also a ton of listings on Ebay for parts. One guy is selling them as "direct replacements" but I'm sure you'd save a bit by getting them at a local electronics shop.
I ordered five 3mm blue LEDs from Small Bear and today I received five 5mm LEDs. They obviously were in a hurry and either read the order wrong or pulled it wrong. I've emailed them about their mistake and I'm waiting for a reply.
In an unrelated event, I ordered a replacment IC for a JCM800 from Mouser Electronics. It shipped in about 3 days.
In the future I'll probably just deal with Mouser.
The guy at Small Bear acknowledged their mistake and said he's shipping the correct LEDs. Funny thing is, I already ordered from Mouser, and received them a day ago. Mouser ships incredibly fast.
