[sdiy] Satisfying DIY

[Tim Ressel]

Tom,

I have the exact same story, except it is a 1971 Chevy
pickup. Can you say 'no car payments'?  I figure the
$300/month payments i was making will keep
"Truckasaurus" (fossilized transportation) in upgrades
and repairs forever, with cash left over. I do most of
the work myself. It is lots of fun, and save Big Moola
come repair time. 

Synth-DIY tie-in? Oh, well, I carry my synth gear in
it... :-)
