In need of a modem.

So our ISP, ponderosa (visionnet) is horribly bad, but is all we can get here.
Their modems, not routers, are very poorly made. My father has one that is currently dying out and he dosent want to go through them to get a new one. So he was wondering if he can buy a new one, and use it through them, They said they can activate one so he needs a modem itself. So if anyone has some recommendations (As cheap as you can get it probably) and preferably in store. Any help would be appreciated.

EDIT: Such as this one?? http://www.newegg.com/Product/Product.aspx?Item=N82E16825165003
 
Solution
Like I said, they are horribly bad. There is nothing on their site other than
▪ Hardware: PC, DSL Modem, USB port or NIC card
▪ Software: Windows 95 or better operating system
▪ Ponderosa dial-tone, and DSL Internet Access subscriptions

They said netgear dosent work well.
