I've looked around, seems like the best deal I can find is about $125 for 40G. Maybe I'm not looking in the right places...

Suppose I had (roughly) $100+- $25 to spend on adding space to my empeg. What's my best deal? Anyone selling used 40's cheaply?

Any particular brands to stay away from? I've had exactly NO problems with my empeg and don't want to create any. Whatever shipped in it works great, even at very low temps. (Riocar Mk2a, 10G)

Thanks for any input.
