You can get quite far with a set of quality basic tools and for some ad hoc jobs even the cheapest consumer tools does the trick. But some jobs just require tools that are made for the job.
Even getting the cheapest tools for a small job might cost quite a lot. And the quality of those tools are what you pay for them. The cheapest ones might get the job done, but the end result might also end up cheap. Also the investment in such tools might be moot as there probably isn't going to be much opportunities to get any return of investment later.
It's better to rent such tools. You get better quality and better results as well. Renting those professional quality special tools is probably going to cost less than buying those cheap, poor quality substitutes. The only problem is that the clock starts ticking as soon as you check out the tools and you need to get the task done within a reasonable time instead of taking your time.
