What kind of cordless trimmers do you own?

I need to replace my old Ryan cordless trimmer/blower and I'm interested in what works for you. I like the fact that the head snaps off and a blower snaps on. The bad thing about it is it has a built in ni-cad battery that takes forever to charge. (old school) A replaceable battery would be a plus and the lithium batteries are the best. The Works that's advertised on tv is highly rated and the adjustable length and edger option looks handy. What do you guys use?
