Charles- unless you're shooting 5x7 or bigger, the hot-shoe flashes should be quite adequate. One workaround for the AC-strobe issue is with many modern power packs, they have a low-power recycle option that makes the pack take longer to recharge, but it only draws a fraction of its usual amperage. Also, if you are working in an apartment, most likely you don't have giant spaces that require gobs and gobs of power to light, so you could dial down the power settings and work with low power on the slow recycle and never trip the breaker.
