Hello........I am in Australia so can't give a lot of advice about saws but I do have a Trupro saw which is the same, I believe, as your Axminster FS18" - the so called Hegner clone. I have had it now for about 4 years and regard myself as a heavy user. The only problem with it was 2 small bearings which I replaced from the local auto shop. I have used many different saws over the years, including the EX 21, and I have to say that I have never used a better saw than the Trupro. It is extremely smooth running and very quiet. Actually, I do not have it bolted to the bench and I usually have it running at about 2/3 speed. A nice feature of it is that it has 2 stroke lengths. The saws are reasonably popular here and I personally know of several owners and none of them are sorry they bought it. I don't know what the price of the AX's in the UK, but they started off pretty cheap here but quickly grew in price.
