The biggest downside with all these 'benchtop' thicknessers is that, regardless of the brand or colour you go for, they're very noisy compared to most other machines. The sound of the machine running (without cutting, not under load) is akin to a cheap vacuum cleaner. Obviously, it'll make a racket anyway once it starts cutting wood but, if you had the money, the space and could find the right machine, I would certainly consider going for a floor-standing model with an induction motor (unfortunately, there aren't many options in the UK market, unless you have at least £800 to spend on a new machine!).
You've already had some great advice, though. It's often worth paying a little more if only for the after sales service and spare parts.
