I just noticed this had 0 replies and I figured a little bump might help get some ideas. Thing is, this question gets asked about 20 times a day on the forum - and unless you provide a bit more information, we're shooting in the dark.
So are you looking for another VV / VW
device or something mechanical?
What is your size preference compared to the VV 3.0 - bigger, smaller, same size?
What are you planning on putting on top of the new
device?
Do you have a good quality battery and charger or would you have to buy these as well?
What form factor do you like - tube, box other etc.?
What is your budget?
There are hundreds of
devices out there - give us a few more details and maybe someone can come up with some suggestions for you.
