2.4ghz asf vs regular ma-010

[94exa2]

i was wondering if the control/quality of these is better than the standard ma-010, or if its just the auto selecting frequency thats better?

also, anyone know where to get the 2.4ghz set? i found 1 on ebay but dont trust ebay too much and dont see any on atomicmods...

(does this have everything i need other than body/batteries?)

thanx guys, still learing these Z's!
