[Amps] Recommend supplier for aluminum sheet?

[Bill Turner]

I need some pieces of sheet aluminum for an amp project.  I've done a
search on the internet and found a few suppliers who will do custom
cutting and sell in small quantities.  OnlineMetals.com has a very
good website and would appear to be a good choice.  I'm in Southern
California, and closer would be better.

Any others you'd care to recommend?

Thanks in advance,
