My son has mentioned he would like some Gravitrax for Christmas. He hasn't got any at the moment and I'm not sure what I need to order so he's got enough to really enjoy it over Christmas. Is a starter set enough and, if so, which one would you recommend? There seem to be lots of different options and I'm finding it all a bit confusing, having never seen it in real life.
Also, is it actually any good? It's quite pricey so honest opinions would be great.
Thanks for any guidance you can offer!
