I have an Orion advanced flight charger which looks similar to the Charger pictured on the first post. Good charger but no balance and no memory for charge profiles. Limited to 5 amp lipo charge.
I also have a Turnigy charger. I purchased the Turnigy charger after reading a long series of posts on another forum. Google the Turnigy charger model and you will find the posts (29 pages)
Most of the users (RC planes) were quite happy with the charger. It's not perfect but seems like a good buy for the money. I have not had any problems with the charger but have only been using the charger for 2 months. Note it is also limited to 5 amp lipo charge. If you want to know what the charger can do the hobbycity.com has a pdf of the opeations manual you can download.
