I bought a glow driver from
www.rcatsystems.com about a year ago. It's got a lithium battery that needs seldom charging. I've recharged mine once now and it didn't really need it then. It's become the go-to igniter on the field when the others are unsure if theirs is OK or not. It's a little pricey but I NEVER have to worry about it.
