That's been my solution for my ham packet stations. Pentium-ones can be
easily found for under $200US (I got one "166" for $35). Batteries are
usually poor or shot but I run them off a $30 inverter anyway. So far
none of the 5 I have have quit (don't go for the door its just me
knocking wood) but if they do I've got my $$$ worth out of them.
