I just got 2000mah nimh Tx and Rx batteries, and need a charger. I'm trying not to spend a fortune here as I'm already over budget. Do I need a charger with a discharge function? Is anything wrong with a $30 peak DC charger http://www3.towerhobbies.com/cgi-bin...?&I=LXDXA2&P=0 ?) Is there an AC/DC charger that will also charge a 12v field battery? Right now I don't have 12V field battery, so I was leaning toward AC or AC/DC, unless I got inexpensive charger and 12V battery (and charger for that too?) I'm totally confused, just want to get what's good for the batteries without breaking the bank.

Thanks!
