2wd buggy choices

[200sx]

I can't decide which midmotor 2wd to go for.
There's quite a good mix at my local club, DEX210, SV, SV2 and TC02C mainly.

I love the look of the SV2 but the DEX210 wins more races.

I don't want to be buying the kit and then having to spend more on getting the car up to scratch so which buggy is more capable 'out of the box'?

Which has the best parts availability?

Which has the most reasonable price spares.

I want a buggy that will grow with my ability. The option of tuning to one extreme or the other, something my Ansmann X2 is lacking. I enjoy tinkering as much as I do racing.
