Oh my, this thread is making me nervous. I ordered a Joye 510 and it will arrive Tuesday (tomorrow is no mail due to holiday). Now I'm feeling that I made a mistake because I do NOT want to be recharging a battery every hour. So should I get a "mega" battery, and does that need a different charger? I want a simple, easy-to-use set-up, but I also want something that works well. Please help with your experience and expert advice!
