Having read this thread on replacement after market fences, I would like to comment that I too have in the past had problems with sourcing aftermarket fences for saws and ended up making my own T-bar style fences with some success. Although fairly easy to manufacture it requires a little engineering and metal work skill which I appreciate some woodworkers would rather avoid.
I feel though there is a huge gulf in the range of saws missing from our market, either we have the cheap bench top models for about £150 then up to about £600 for the entry level cabinet saw. (assuming saw benches rather than bandsaws but applies to them equally) Then from around 2-3 grand and upwards. There are of course saws priced between these ranges but they just appear to have little bolt on gimmicks rather than an improvement in the saw itself.
Most of us suffer from the same problem, lack of space, this being the case a saw of bench top size with a decent motor, trunnions, cast top, blade guard/riving knife, handwheels and decent fence etc would, I am sure appeal to most users because of its compact size with reliable and quality build. With this would come many after market accessories to customize or improve the base version. Some of the fences on these cheap saws just seem an accident waiting to happen.
Just an opinion.
