If you are looking for a dedicated thicknesser rather than a combined Surface Planer/Thicknesser then I would highly recommend the Axminster TH410 - I bought one of these a few months ago and I cannot fault it - with thickness boards up to 16" wide , variable feed speed and with the digital display can be re-set exactly for repetitive work. The machine is about £850 and the digital unit approx £30.
The finish is spot on and I have used it for oak, elm, beech etc and had no issues with it whatsoever.
Gets my vote anyway!
