Power quality monitor -- cheap?

I'm looking for the most economical means to monitor mains voltage for
spikes
and other such disturbances over an unattended period of time.
I see that there are 2 categories of monitoring and logging equipment:
event
loggers and samplers. The former requires the setting of thresholds and
will
record any event that exceeds these; the latter simply samples the input
at a
set interval.
I am looking for a device that records events.
I'd rather avoid the very expensive power quality monitors ($2000-plus
category). This reduces the list to DMMs with logging capability, which
includes the Fluke 189. (I'll add that if a data-download option exists, I
would prefer the ability to review data on the device rather than
*require*
that it be downloaded -- I want to be able to, at a glance, confirm that a
power problem exists, and have the *option* to download the data for
detailed
examination if I wish.)
