[PSUBS-MAILIST] Psubs Barge

Fri Sep 5 20:12:18 EDT 2014

That is outrageously good, and the cost is crazy low for the result. Plus, I love the small items you just happen to have lying around in the parts bin. 

Hank, we should all just buy it off you for two grand so you double your investment, and we'd still be getting it for a small fraction of what it would cost new.

Best,

Alec
