May I point out that "synthesisers" may have a web site but that is just the online presence of a fully functioning retail outlet (Hamiltons of Preston) which I pass most days whilst commuting, and have used sometimes. They are certainly not a bunch of anonymous and unknown box shifters, they do know their stuff.
But you do need to read the review with the knowledge that (I believe) they are official Yamaha and Roland dealers. I've seen some serious Korg stuff in there as well. I think the review is genuine but will have been written by someone who will be trying to sell the product and so naturally is going to "accentuate the positive".
Of course they'd love to shift bucketloads of Tyros 4's - when all is said and done that's their job, but doing that around here in the current economic climate it going to be a very hard task no matter how astonishing the Tyros proves to be.
As ever the opinions I'll trust most will be (a) my own and (b) anyone else on this forum. I haven't seen any publicity locally about demonstrations but if I get the chance I'll try to attend. Regrettably I'll still only be able to afford one by winning the lottery!
