I am currently using the transmitter/controller issued with my HL Pershing. What would y'all recommend for the next step up for a new controller?

Thanks for all the help on the accessories issues, I have ammo cases, mine detectors, figures, netting, scale radios, packing gear, sandbags coming to my house and hopefully in 10 days!

I would like to upgrade my controller though. Something to 'fine tune the performance' and a new battery/charger system upgrade as well.

Thanks again
