Me get my 1st vstank leo A6 to start my rc tank.. It was really fun, which can do battle w/o buying any battle kits. right now, i going to upgrade my tank to tamiya.. Because of the limitation on vstank nothing much. Cannot play outdoor due to IR not very good. When i first play tamiya tank, the feeling is different.. I like, wow, got engine startup sound, idle sound n shut down engine sound too.. Tamiya battle unit oso very good for outdoor battle.. As for HL, if u got limit budget, u can try. But i seen many peoples buy those Elmod or other 3rd party to mod thier HL, it's usually cost up to tamiya tank value.. AND, after u mod, it electronics will sometimes HANG or reboot if u do many things in one time.. My friend have a HL Pz3, the look is toooo plastic not very detail worse than vstank.. This is only my point of view, it up to u to choose. No hurt trying all tanks. Have fun.. U will love it.
