Hi there Dad..
Having built and run on many different types of track over the years, home and club use, If you have the room, and you dont want to go down the routed wooden track route, then go for Carrera track.
Its nice and wide, so 1:24th cars can run on it ok, has stainless steel rails, good track surface, and very tough..
The only downside is that compared to other makes, it is quite expensive, and there are no very small tight curves available, the smallest radius is quite large, so you do have to have quite a large area for a good size layout.
My own home track is a four lane Carrera, and I have found that almost any make of slot car runs on it, even my event cars fitted with the deep Slot-It guide for wooden tracks.
All the best.. Martin De'ath.
