I can only agree with the two comments above. I have had a set for over 47 years, though interest had been on and off depending upon what life had brought. Been really fortunate to have the space to build a big shed and fix a permanent track - running digital through the advanced powerbase.
I have had various nephews nieces and in-laws using it, plus neighbours and, I am pleased to say, all the youger members have bought tracks of their own to wreck, instead of vandalising mine! Sorry, that should say - enjoying their own tracks and using them well....
It is the digital system, with all the lane changing, pit stops and pace cars that has them hooked - even the youngest at the advanced age of 8 said that it is much better than his computamabob in to which, he normally has his nose fixed and eyes glued. He now has his own set, having matured to the age of 10, which was fortunate for him after he nearly wrecked Jim Clarks Lotus 49!
SO, I think there wil lbe a good future, but, come on Scalextric, let's have something official to at least match SSDC.....PLEASE!
