So i guess this is what im going to order the 510 SE with some boge cartos are there any better pvs out there? I have been using bloog for almost a year even though i love it kinda of getting tired of charging batteries all the time and was thinking some of the cartos for the riva could hold more juice mabey not now that i have checked into it. I would love any input on what to buy or what not to buy b4 i order today thanks
