new dsl modem

qwest is now refusing to check my dsl line until i replace my venerable cisco 678. the recommended replacement is the gt701-wg. it actually looks like a nice piece of hardware; i'm amazed that qwest made a good decision on something. they couldn't fool me into ordering one from them, though. $100? i found a pile on ebay for $30-40. i'll have to set it up myself, but i wouldn't trust a qwest tech to do it right, anyway. besides, when i called their tech support about it while setting up the ol' 678, i always got the same thing: 'i need to know the settings to put in so it will connect to your hardware on the other end.' 'what operating system are you using?' 'ah, i don't see what that has to do with anything. it's an external modem.' 'well, i need to ask what operating system you're using.' 'linux.' 'we don't support linux. goodbye.' on a tech support call, i can find people reading a flipchart. on the web, i can find people who have done it.
