Sup Gomer! I've been using the KO PC-101L for over a month now and feel it works very well. It doesn't have setting memory like you mentioned but it's extremely easy to adjust. It has a built in fan so I can charge batteries almost non-stop. I use to own a Hyperion 0606i and always had to run an inconvenient fan over it. However, the Hyperion also work good too. I have no experience of other chargers so I can't say much else. Oh, it's also convenient not having to carry a power supply like others do. I guess I'm not that hard-core

Let me know if you have any other questions.
