Don't mean to crap on this thread, but since many seem to be disappointed with the Mach2 I have a suggestion based on experience. Unfortunately, its at Fry's and many people don't have access to the store or just don't like it. I have bought for myself and friends, 3-4 of the "56K PCI Internal/Fax modem" SKU # 2792663 that they sell every week for 20.00 with a 20.00 rebate, so they are essentially free. These modems are made by Actiontec and they perform great. The rebates also come when they say they will, 6-8 weeks. I have bought 3 different Actiontecs for my various computers ( 2 models of PCI and the USB call waiting modem)and everyone has work nicely. I get consistent dialups of 46,666 to 50,333 with no dropped connections. Just a suggestion and you can't go wrong for free.
