Yellow HeNe tube

Might be a cheaper alternative to DPSS yellow for someone, right now it's bid up to $100.00 and has 20 hrs left:
YELLOW 594nm HELIUM NEON LASER TUBE MELLES GRIOT HeNe - eBay (item 120459475302 end time Aug-25-09 17:29:53 PDT)

I also saw a green HeNe on Ebay the other day, but you'll have to search for that one as I don't have the link off hand now.

Wow, that is a great deal! For anyone that gets this, I have to warn you, the power supplies are hard to find for a good price. I've been looking for a spare one (as my 10mW red HeNe and 4mW yellow HeNe use the same power supply) on ebay for weeks, but haven't found anything reasonably priced. Anyways, good luck to anyone who gets it!

Very cool SL! I will not bid it up, but, I wish I could get one of those! -Glenn
