Yes a trades person may well know (should know) the benefits of a particular tool. But in context of this and other "recommend a tool" threads, the person who needs to ask that question, especially if a DIYer, won't know the difference between a £200 drill with a brand name or a £19.99 special from Argos or Aldi, and I doubt will get any benefit at all from paying the extra just for the name.
Yes, I agree with you. I was always taught from an early age to always buy the best you can afford as it saves spending more in the long run.
I have heard good reports of Lidl's cordless drill range and don't doubt that for DIY'ers they are good value for money.
