retnuh,
I'd recommend the Hobbico charger that does Tx and Rx batteries. I have not found a need for a cycler in my years of modeling, and my batteries have lasted for a very long time. To cycle your batteries, just run them down and put them on your overnight charger for the length of a good, full charge. I went quite some time without a field charger, but now I don't know how I made it without one. One of the uses I found for it is when I'm not planning on flying but the weather turns out perfect. All I have to do now is quick charge my packs while assembling the plane at the field, rather than sitting the day out. In addition, you might find that you left your receiver switch on by accident, or even the normal reason that you are having so much fun flying that your batteries are getting low. In addition, if you go to larger planes then you are going to need one anyway, so have fun and get in on the action now!
