I never have problems with the batteries, it's always the attys or carts. Carts are no big deal as they aren't as expensive. I've looked at mods but was uneasy about that since I want to order something NOW and it should be something I'm mostly familiar with. I will take a look at the great suggestions you have posted here. I don't know of any local shops.. I have a friend who sells (who got me hooked on this in the 1st place a year ago) but only 808 and no juice. Anyone know of anyplace in Seattle?
