I have this
https://www.screwfix.com/p/titan-ttb579pln-204mm-electric-planer-thicknesser-230v/15774 and as a thicknesser I've put loads and loads of stuff through it. The engineering is a bit agricultural and as a planer fairly rubbish as the tables are not robust enough and the fence likewise. The Rutlands machine linked to above looks incredibly similar (as do the scheppach and zipper machines) but is a lot more expensive, but looking at the images of the bearing side I suspect even if there are some detail differences the rutland one is identical inside.
I have adapted the thicknesser plate with a long piece of plywood to better support the timber, and also done away with the plastic guard (and associated safety microswitch) and replaced it with a plywood guard. It produces so many chips I don't have a vac powerful enough, so I mask up (and ear protection - it's F loud), let the chips fly and pick them up afterwards.
Keep the chain and plain bronze bushes lubricated
Mine is good for a tolerance of about 0.1 - 0.2mm across the board being thicknessed. Although it says up to 2mm off per pass, in reality it's more like 1mm or 1.5 at most. Better to take smaller passes.
The erbauer and titan blades are identical, and take a load of faffing to change and level up, but are secure.
Drive belts are available. I have spares but have never used them
