[McMurdo]

I had some a few years ago from a local electronics shop, now defunct. It also had shorted strips, definitely an etched board as the copper shorts looked like a web that hadn't dissolved properly.

Some of the tinned, and expensive board sold by Farnell from a french manufacturer has the offset hole problem, it's been reported on the product review section by a user.

I'm pretty sure some of the electronics hobby suppliers used to sell a sanding block designed for bare copper veroboard. If I'm not using tinned stuff, I always go over it with some fine wet & dry first. Makes soldering so much easier.
