After reading through the recent post about the Seacraft sinking, I decided that I needed to rig a dual-bilge pump system in my boat(which I should, hopefully, be getting this weekend).
It seems that the consensus was two bilge pumps, wired to separate power sources at the battery switch and set at different heights, with one as a back-up. Also having each bilge pump the water out it's own side of the boat, so that you would have a visual warning if your primary failed.
In addition to two bilge pumps it was also recommended to rig a high water alarm.
After a lot of searching on the internet it seems that the Johnson pumps are the next best thing after Rules(which according to the Martha's Vineyard thread are now Made in China garbage).
I also found these came highly recommended on another site:

Right now I'm thinking on going with two Johnson 2200GPH pumps, and getting the rest of the hardware from that site.
What do you guys think?
