A simple, very low cost method here. Drill an appropriate size hole in your master cyl cap, cut a small vent hole in the cap's gasket (diaphragm?). Epoxy a tire valve (Schrader Valve) into the hole in the cap. Fire up the compressor with 5-10 psi attached to the tire valve, don't let the reservoir get too low as you bleed each cyl/caliper singlehandedly. It's worked great for me on three different vehicles.
Hope this helps somebody.

The pressure bleeders are ok. Most plastic reservoirs are just pushed into a rubber sleeve though so be careful not to much pressure or you'll push the reservoir off the master.
Nothing beats a good old fashion high pressure high volume brake peddle bleed though.

Sorry guys, I'd left out a key step....epoxying a tire valve in the hole on the cap. You don't need to cut the diaphragm if you're leary, simply remove it and install a temporary rubber gasket cut from stock. You just need to seal the reservoir enough to let the low pressure air do the work for you. PS, you do need a clamp-on air chuck. PPS, when done, replace the temp gasket with the diaphragm and cap the tire valve.
