Scored this at a community flea market today (items are donated and sold for mostly arbitrary prices as a fund raiser for the school that hosted the event):

$15USD.
Sounds like shit through the built-in 12-inch speaker (bad speaker?), but is actually pretty nice through the headphone jack.
The best part was when the person quoting me the price suggested that I could test it to see if it worked by plugging it in to a nearby outlet. I left my guitar in my other pants, so I had to buy it as-is, but the price was right, even with risk of it being dead.
I acquired an old Harmony solid state amp that looks very similar. It had a 10" speaker and sounded "meh" but was a nice little bench amp because it was totally neutral. On a whim I installed the 12" speaker pulled from a Blues Jr. when the owner upgraded and it completely opened up the amp. This thing rips. It's still my bench amp but its great for pedals because I get a really realistic view of what the pedal sounds like. Very little coloration and tons of headroom. It's the one instance of not-having-a-personality is actually an advantage.
Felt I should briefly update this story:
After lots of elbow grease (mostly with rubbing alcohol and cotton swabs), plus a new speaker.

I actually like this amp a lot more than I expected to. ;D
