The Vega cars are getting out there, last batch of B4 ones there were over 30 pre sold, I am sure they will be hitting the tracks soon!
At my local club there are 6 vega's already, mostly B4 and 1 x Kyosho.
The pictures dont do the car justice, the machine work is amazing, go for it!
As for support, you have some top drivers running it, maybe not as many of the B4 version but you can cross over set ups and get it how you want it.
Lots of oople people are willing to help, Kev Lee, Nicvega, Tony Evdoke, Alec Springer all top racers and I am sure the list will grow!
