I've had about three local ISP's in the last ten years...by far the longest
lasting has been QNI (now http://www.primary.net).  Fairly low user/modm ratio,
good tech support (at least in the QNI days...I don't know if that's changed
with the primary.net take-over...haven't needed to call).  They even had SWB
change out a switchbox  when I was getting spurious disconnects.  No
complaints.  Both the Linux box and the Newton connect fine.  (No non-local
access number for vacations, though...bummer)

A friend has kcinter.net, and I can just about figure there's a thirty percent
change that my mail to him will bounce with an "unknown user." :(

Haven't heard any complaints from friends using blitz-it.
