I have owned the 8" Vertex for the last 10 years. It works perfectly. I converted it to CNC 4th axis about two years ago. It has a worm drive with backlash adjustment on the worm and on the shaft. The Vertex is the only one of the three where the maker (Tawain not China) is prepared to put his name on it, together with a test certificate. Generally Vertex has a good name for low-end equipment, you do get value for money and no boat anchors. The main spindle has a taper roller bearing and the worm shaft has a thrust bearing (ball), but strangely only one. I added a second when I converted to CNC.
Personnally I would skip the HF table. No tolerance specs, crap manual, no mention of backlash adjustment, strange design. It has all the hallmarks of a boat anchor.
Just some thoughts and opinions.
