Anyone here into slot cars (we call it Scalextric here in the UK)? I've recently bought a set now my boys are old enough (although my 1 yr old girl is pretty good too actually). Reliving my youth mainly (I'll be having my midlife crisis in 10yrs or so

).
I'm pretty surprised how good some of the cars are now, there's some manufacturers I never knew existed making decent stuff. It was only Scalextric (the brand) as I was growing up, and they still dominate in toyshops, but Slot.it (to name 1) make cracking cars.
Anyway I'm not sure of the current level of interest in slot cars in the US (they've made a comeback in the UK thanks to a TV show with James May, Top Gear presenter), but if anyone's into them, or has fond memories of them, please contribute.
