A 720W offline switcher kit?  Be sure and warn people to use an isolation
transformer during checkout, if they're gonna be 'scoping the waveforms!
I'd also check into the magnetics--might not be easy to get in the core
sizes in the (smallish) quantities you'll need, unless it's a wind-your-own

We recently bought a dozen or so industrial 110Vac to 24Vdc switchers
(10-20A), and looking at the board, I'm not sure that you can do a small
kit run for less than the cost of just buying them outright.
