My goodness, I've seen so many saws like this. Some are painted yellow, some are painted red, yet no matter what the colour scheme they're essentially the same Chaiwanese saw that is aimed at the newbie market. Sadly, people who buy this type of saw splash out a lot of good cash in the belief that anything which costs so much must be good. It's common for them to visit a forum such as this and celebrate their new acquisition, only to fade away after a few weeks and never surface again.
Before you buy this saw, please review the advice that seasoned scrollers have offered here generously, independently and honestly. Consider the so-called 'reviews' on the website and think about how many discuss the speed of blade change, its suitability for piercing work, its vibration and the many other qualities that scrollers on this forum think are important in selecting a scroll saw. There are seven reviews, all of which give it a minimum rating of 4 out of 5. I wonder how it would fare against a Hegner or a AWFS 18 or a Diamond? Heck, if I could buy a saw with a 4 out of 5 rating for £167 (reduced to £101 - I wonder why?), why would I consider a saw such as a Hegner for several hundred pounds more which, despite its many pleasures, is nevertheless imperfect?
Although I have not used a Sealey, I have used Hegners (and Diamonds and DeWalts). Somehow, I suspect Hegners will be around when Sealey's are long forgotten.
