I am installing a new kitchen based on Homebase units. Homebase used
to offer a nice easy way of doing corner joints on worktops using a
product called "pro-joint":

Due to the law of sod, they have just this instant stopped selling
this product and the manufacturer has also stopped making it. I have
read a few posts on this group and the web at large about the expense
and difficulty of either mitre or router constructed joints. Has
anybody heard of another manufacturer that produces a "pro-joint" or
similar product to save me from this hassle?
