Hello,
I've just been looking for a kitchen worktop jig on t'web and looked at the usual sites. But I'm in France and the sites here seem sparse. (searching for 'gaberit d'assemblage plan travail)
The ones I did find were over 300 euro (+ tva) and the only cheaper one was sold on ebay for 100euro Heck that's more than I paid for the worktops.
Looks like i'll be paying postage from UK
John
