I am going to be in Frys Electronics in Phoenix tomorrow, and I would like to pick some up, but I am not sure I will be able to find that exact chip
I live near the Fry's on Thunderbird. If you've never shopped Fry's for electronic components, get ready for some fun. They are a distributor for NTE Electronics (http://www.nteinc.com/);
some of the their parts are "standard numbered", but most have an "NTE number". Your best bet is to find the NTE parts catalog somewhere on the shelf, thumb through it to find the part, then find that part on the shelf/pegs. Fry's doesn't carry all of the parts that NTE supplies, so you may find something perfect in the catalog, but it won't be on the shelf. Fair warning.
What I typically do to find components is shop online - Digikey and Mouser (and a couple other places) if I need "new stock" items. If I can go with surplus, but I need it fairly soon, I'll use Electronic Goldmine (in Scottsdale, web only though); otherwise if I can wait a bit longer (sometimes the difference is minimal) I'll use All Electronics. Just about every weekend I'll go down to Apache Reclamation and Electronics in south Phoenix to check out what they have (if you don't know about this place, you owe it to yourself to check it out). Beyond that, it's Ebay and chinese suppliers.
Good luck finding your parts.
