I was just wondering if anyone is into there scalextrics on here? I'm wanting to build a big track in my attic for the kids to use (And me after a few beers

) but I think it's changed a bit since I was a kid, they have digital cars or something now with brakes and you can run more than one car on the same track
Can you get a "normal" one with just a trigger that makes them go round the track or is that a thing of the past
I'd buy all the bits off ebay or from the local freeads but I need to no if there are different types of track and cars that aren't compatible with each other, and if I go to a shop and ask for advice I can see me getting ripped off or them trying to sell me a box set which isn't going to be big enough for my plans.
Any information, advice or links would be appreciated.
Thanks in advance,
Chris
