My personal favorite is the Crono Stainless Steel Box. It's a direct drive, single 12V motor that will turn over even the most stubborn hot rod engines when they are new. It's much simpler to set up for your car than the regular 4 post locater style, and the switch and wiring are the stoutest I've seen in any starter box. I prefer to hard wire (solder) my starter box connections and the Crono box is the only one I feel comfortable doing this with. The switch bodies are made of a heavy, heat resistant material that won't melt 2 seconds after you put your soldering iron to it.

Regards the on board power panel. I've never had any luck with them.
