Radonseal sump pumps

Does anyone have any info or experience with the RH-1400 backup sump pump by radonseal company (Novion inc) out of Shelton, Ct?
It's online ordering only and I want to be sure it's worth $390.00 before I invest in one. Any other recommendations for a pump that mounts outside of the sump?

Slogdog:

I saw your post when looking for information about Radonseal pumps. I was thinking about getting one of these pumps and was wondering if you ever got feedback on them, or if possibly, you bought one. Did you have luck finding any other exterior pumps? That is exactly what I need.

Oops - Slodog. Sorry.
