rapidrunner bilge pump systems

I want to get an electric bilge pump for my QCC 600s. The rapidrunner system looks good and, with a few extra parts, can be switched from boat to boat. You can check them out at rapidrunnerbilge.com. Does anyone have any experience with this company, or have other suggestions for something commercially available?

I have the lead and lithium systems
I initially wanted the lithium system as I am an open boater, but the batteries were on back order,so I bought the lead system which is great. I also purchased the lighter lithium system as I have some long portages and it is excellent. The owner can be slow to respond to emails, but quality systems.
