Buys the Drake DSR-2 for $725 on Ebay and sells it two weeks later for over
$1100. Not bad.

Not too good either. A lot of high-end retail has dealer margins
significantly higher with much less risk (although a higher cost of
doing business) than buying "high" on E-bay and selling "higher" on
E-bay.

Some rather business-savvy folks advocate that the optimal E-bay
sell:buy margin is 30:1, with good arguments. Anything else is just a
hobby.
