HEXBUG Fundraiser for all FIRST teams

[gburlison]

So I picked up a HEXBUG at Radio Shack to show off to the team. We are considering this as a fundraiser. I have demoed it for our team and many of my friends. Now the batteries are getting weak and I am having a hard time finding some new ones.
Does anyone now of a good source for coin/watch batteries?
If we sell these we are also considering selling replacement batteries since they seem hard to find locally. My HEXBUG had an L1142 battery which cross references to 386, SR43, G12, and R43W among others.

I finally found some in the jewelry dept at WalMart and paid $3.77 each, hopefully we can find them cheaper somewhere else.
