Well, there is this one:

$25 + $1 for shipping. If you bought 2 CellPro packs instead of 2 Scorpion packs, you would save $23, which means that you would have to spend $3 on the Lisaver. The important thing to remember is that over time, it would be cheaper to get the non-Scorpion packs and just use an external LVC (or a controller with this feature built-in). That is the main point I am trying to make.
