The AT460SS is a very good saw, it is as said the Hegner clone I have its forerunner the AWFS18 but its the same saw
You said something about blade changing, the Hegner has one blade change block on the side of the table, whereas the Axminster version goes one better and has two blocks spaced to fit a blade with two V blocks, but as you will know the Hegner quick clamp is far better on the top, but the two blocks are very useful all the same as it lines up the blade dead straight
Ah, no the penny just dropped, you mean the slot in the table itself , the Axminster doesn't have that but I have not found it a detriment, just move the extraction port down, its hinged, push the blade up through the aperture, and the bottom V block pops in easily, I do it all the time without looking, its no problem at all
The later models have a modification of metal bushes on the quick tension lever but they can be retro fitted if they are not already (although I used bearings off a spare set of router blades which I feel work better)
So in a nutshell, yes its a good buy, even better if you can get a used one for around £200 to £250
