I would not switch. The Prodigy 625 does everything you need. I have raced R/C for many, many years and have had every type of charger out there. I have been using a Prodigy 625 for about a year now and love it. For a cost to value stand point , I think its the best charger out there. I actually pit next to a guy every Sat. night that has a I charger 406 and he likes my charger so much he is going to switch. He likes the built-in power supply and the 625 does everything he/you needs. Actually they started checking battery voltage at my local track and my charger is a lot more accurate at reaching the set end voltage then is charger. He actually had me "topping" of his batteries until he figured out how much he had to over-compensate is end voltage to reach what he wanted. Stay with what you got. Just my opinion though.
