Scorpion packs

[Batfish]

Papa - I'm with you on this one. I think the Scorpion packs are worth the extra money for the benefits and features they provide. I'm tempted to buy a couple Scorpion packs at the new low price myself. I have the BalancePro packs (the original BalancePro, which is just like the Scorpion except for the cutoff) and they have performed exactly as advertised.

I would not hesitate to buy more FMA/Kokam packs, provided the price is still worth the features and benefits.

That KO Propo supply you list is a decent price for what you get. The power supply that MetalMan links to would also suffice for the Scorpion charger. Mike should be able to get you good pricing on a power supply if you ask him. Lastly, I use a 25A power supply that you can get at your local Radio Shack for $99.
All of these options are valid for a power supply. Choose what you like best :)
