Mesh sell many thousands of computers per year and irrespective of what you may hear, the number of complaints are tiny and probably no more than any other manufacturer.
To put this in perspective, PCWorld seem to have a large number of complaints on this forum. I've now bought over 20 computers from them and an astonishing amount of hardware. I have never had a problem or met an 'idiot' sales person. I've met sales persons who are very switched on and some who are not the sharpest knife in the drawer but this is a mirror of life. A certified Sun Systems engineer would hardly be working for PCWorld ;-))). You also have to remember that you only read one side of the story on anything sent to this forum. Mesh, at least, have the courtesy to have a presence here and if you are worried about paying for helplines (premium rate is not uncommon) then you have here, which is free.
Many of my friends have Mesh computers and as far as I can see they are a good piece of kit. The current Mesh range is superb value and if I were buying a new computer I would be torn between teh Mesh 3000 click here, teh Medion, when Aldi/Lidl are floggin'em or teh Ionix click here
Every manufacturer has had bad publicity but one has to remember that ones that are still trading after many years must be doing something right.
