1/24 Scale Cars?

[jfoxh]

Hi, got a lot of questions here... bear with me.
I've just discovered 1/24 cars, been running 1/18 and 1/10 for awhile. Recently, I have been looking at the ABC, Aktiv, WWS, and Mini-Z. The Aktiv car is very nice looking but way pricey and the Mini-Z seems a bit more like a toy. I'm guessing the ABC falls in closer to the Aktiv car, at a much more reasonable price. The only problem with getting an ABC seems to be finding parts, while the Mini-Z is all over the place. Are the parts for the ABC hard to come by?Also, which car do you guys prefer, the SP or the X4? Where do you all race your 1/24 cars? I'm in NC for another month then up to MA for the summer, anyone race in these states?

Thanks!
