Outgoing faxing

I have two kinds of questions about how to send faxes under SuSE Linux 10.0. First, there seem to be two competing and incompatible packages: sendfax and hylafax. How should one choose between them? Second, I'm having some difficulty locating appropriate hardware. The very common PCTel winmodems aren't supported under the 2.6 kernel. External modems avoid the driver problems but are a pain to deal with. Does anyone have some reasonably-priced PCI modems to recommend? I need the modem only for faxing, since I have cable Internet service. Paul
