Funny, seems like several people have come in to the HTX-202's and questions about them in the last few months, and I just got 2 of them for real cheap money. It's all coming back to me on how to use them too, great shape. I'm not getting rid of these, if I do only one. One needs a memory battery but I'm thinking if I'm going to get that and replace it or have someone do it, I might as well do both. Does anyone know where to get that lithium battery by chance? I'm going to get a cigarette lighter plug and keep one in my girlfriend's car probably, not sure on the other one yet but I'm surprised how nice these are for what I paid.
