Agree JimiJimi, it does look interesting. And I've wondered about it more than once.
BUT, though I've seen it advertised several times before, I've NEVER seen any video or written review by anyone who's got one (apart from comments on the company own web site).
And: it's not exactly cheap for what is primarily some plastic moulding (albeit accurate, hopefully) plus some "nuts n bolts";
And: I don't think it does anything that a scroll saw with applicable blades will not do;
And: there are a bunch of similar ideas on the internet to make your own.
I don't want to pour cold water over the thing without seeing n trying it, but I do wonder if this isn't just a gimmicky thing that would end up right in the back of the cupboard once the first flush of enthusiasm has worn off.
Anyone with any experience of this actual device have any comments?
