John, Sorry to here you are still having trouble with supplied equipment being "not fit for purpose" to the standard expected at the price level.
Having said that about price point even a very cheap table saw with a slot/blade alignment error can be a serious hazard.
I am becoming more and more disillusioned about the lack of 'finish' to supplied equipment regardless of price point. I realise that the members of any wood forum are more likely to voice criticism of defects/poor setup etc. but it does seem to be a trend.
I am used to receiving large (very large up to 60 tons) equipment and having to set it up (fettle it as many here would say) but that is to be expected with the risks of transport knocks etc. but the lack of readily adjustable alignment ability on guides, tables arbores etc. points to either very poor initial design or a production cost cutting move to far in the initial assembly.
This latter can occur via not enough quality control, be it at the original designer/manufacturer or at the lower tendering subcontractor.
On most of the engineering equipment, regardless of source, that I handled it came with check lists for alignment and pointers to adjustment methods if they were not established industry practice. A jig-bore or co-ordinated measuring machine is never going to arrive accurate, (try proving that it is measuring within a couple of microns when it's zone tolerance can be just that dependant on temperature) but the slots in something like a table saw are a no brainer, at the worst they should require just a tweak on an adjustment screw not the fileing of slots as I had to do.
Being in the market for equipment myself (in the low hundreds price point) leaves me with misgivings as to the state of finish supplied. Needless to say if I can't get satisfactory answers/views of the innards at the next round of shows the short listed items will drop of the list.
Rant over: I feel better, sorry it will not help your problems though; hope you can get a satisfactory resolution.
