maybe the powermax -HiPac ?

Someone trying to "help" the inventor/owner (?) made posts about this unit here a while back, the posts were, well, poorly written (that's polite eh?) and many people were not receptive to said posts. This was before it was available. It is now available and seems to get good reviews.
Should you try one please let us all know how it works.
