Many thanks for the advice, guys. I've emailed the vendor and await his response. One way or another, I'm going to end up paying for the postage so I don't mind sorting it out to my own requirements. Thanks for the link, Jim; I've emailed the company and something should get sorted out soon.
It's a saw that few people outside the scrolling fraternity are familiar with because the manufacturer doesn't need to advertise it. He's a retired engineer of the James Dyson variety. He saw what was available on the market twenty years ago and decided he could make something better. Unlike Dyson, he doesn't aspire to global domination; he just wants something to keep his income ticking over. Those who have used Diamond saws reckon they knock the competition into a cocked hat (including Hegners

). At the price, I couldn't resist it.
As Frank insinuates, it'll come into its own for cutting thick hardwood and stack cutting - up to 4" thick according to the manufacturer. I can't wait to get my hands on this beastie; with a 1/2 hp motor, it's a serious piece of kit

.
