Cheap tools also have their use sometimes. For example, you wouldn't use your best Irwin or Marples chisel to cut away a piece of floor board incase you hit a nail (maybe you can't be bothered to go back to the van and get out your multitool or don't have one in the first place to hand). You might only be working with rough sawn timber on a building site, in which case you don't need a £30 Stanley Rabone combination square. Just a basic £10 set square will do the job before someone decides do tread all over it or drop it in the concrete footing you just laid. I hate cheap power tools myself as well, but sometimes they can act as a cheap backup in emergencies. Having said that my blue Bosch professional router blew up last week after very little use. Sparks, smoke and a burning smell. Rather annoying. If it was a cheap £30 Aldi router I wouldn't be bothered. A £150 replacement is harder to swallow.
