300£??? Lol Some people have no shame,
look around on internet you can find sellers or join the official Tatará owner group on Facebook and ask to UK user where they cut it.
For a single cut fair price(+-10%) is 90€ for carbon steel and 140€ for Inox 304.
But you can find on internet at 65-70€ for carbon steel.
Is just a advice we do not have any sort of connection/agreement with ANY internet sellers.
Furthermore we believe you can find more honest laser cut service close to you.
