I want to put in a solid countertop in my kitchen. However, I
discovered that the ones I found locally (Corain etc ) aren't
available for the DIY.


I'm an experienced wood worker and this doesn't seem like a difficult
very difficult job especially in my case a straight run of about 10
feet.

You could take the training course that Corian offers.
I don't know how much that costs.

I'd go with a Corian installer.
That way you get a lifetime guarantee on the countertop.
In my case, it was worth it.

Also, if you put your microwave on a Corian counter,
but something underneath the microwave so that counter
doesn't get too hot.
