I've got the Ninco Master Track, had it about 3 months. Very impressed with the track and all accessories are top notch, the power lane will allow for the attatchment of a second tranformer to smooth out the power demand. It is the analog but can be converted to digital with a little extra cash.
I like the scaletrix cars best for the durability, like the earlier poster my F1 were junk after a few days of crashing/racing. The revell cars are fast but not as well built and have broken faster than they should have.
The set up is on a 4x8 and has 37 feet of racing. I got mine online for about 350. I will attach it to the board eventually to allow it to fold up to the wall to get it out of the way.
My 7 y/o daughter is gotten pretty good at it. Enjoy.
