One store that isn't that much in the East (as far as I know), is Fry's Electronics. The best store, EVER!!!! Got my eMac there for $1100, with free printer that I gave to my stepson. (I have the need for a more beefy printer). He uses it for school work, and it is very dependable for him. If I were to buy my eMac at the Apple Store, no printer. Fry's always has little specials like these.
Anyhoo, here are a few choices:
Compaq Presario 6200CL AMD Athlon™ XP Processor 2800+ with 512MB, 120GB, CD-RW, DVD-Rom, Refurbished - $449.99
GQ 6074 AMD® Athlon™ XP 2400+, 128MB DDR RAM, 40GB Hard Drive, 52x CD-RW, 56K, NIC, Windows XP - $429.99
Compaq SR1110NX Celeron D325(2.53GHz); 256MB, 40GB, CD-RW, 56K, NIC, XP - Regularly $479.99, now $429.99
Good luck!
