Now I am a bit confused. I looked up the Ranco on their site, and it holds 1500 watts (the Helix does 500) and has the powerstrip attached; so I would have to buy the strip seperate for the Helix? Not a big deal, but why the huge price dofference? (Helix is $130, Ranco os inly $75?) I just want to learn all about this before buying.
