My comments are in line with most are reporting here. I ordered on-line a PIII 1000 100 MHz FSB from them. They had the lowest price on this item. Most other places had a higher price and not in stock. Next day I received a message from them (can't remember the last time a place I ordered from called if there was a problem!) that they would not ship to an address (my work) that was not approved by my credit card. Let my card company know it was okay and called Dallas Mem. Phone was quickly answered, minor problem quickly resolved. Sure enough, 2 days later the correct item arrived at my work address. A happy customer here, and I will order from them again. Shipping prices do seem a bit high, but you'll still come in under what others can deliver it to you for.
Summary:
1) Great retail CPU prices
2) Prompt, curteous service
3) No on-line indication of stock status
4) Email notification of item shipped would be nice
5) Shipping a bit high
