I was looking to buy the Mitt set but was wondering if the website is still active?

Going from this website: http://mittskateboards.com/en/65_fingerboards.html

Thanks in advance  

here get them from flat face
http://www.flatfacefingerboards.com/mitt/

Cheers will do when I get a deck but I was looking for the kit with the tin and other bits

I'm not sure If this topis is still current. The english version of Mitt website is not working itself, but you can buy their stuff http://fingershop.pl/en/3_mitt or http://sklep.mittskateboards.com/ (unfortunately in polish).

Box rail is sic but pricy!!!

Well, it costs 65 zł, which is equivalent to 15,63 € and 13.81 £ (you can change the currency on their website). I wouldn't say this is pricey.
