I bought just a thicknesser, but I suspect it equally applies.... In my experience do not go for a clarke from machine mart. I thought I was saving a few quid but it was so out of alignment I could not adjust it to get it square.
I went for a jet. spare parts are expensive though... I snapped the drive belt and found that out. Then I found a local firm who matched it to a local manufacturer's version that was a fiver.
