IIRC my aldi jack cost about £20 (always use stands so wasn't bothered about an expensive jack), Halfords ratchet stands were about £25. Don't own a wind back tool but ECP has them for just over a fiver when it's time to do the rear brakes on the Megane.
I tend to way up the cost of any specialist tooling required for a job, if I can do it for the same or less then I do. Next time you do the job its parts only.
I even make a few quid of work colleagues with spanner alergies doing the odd basic service/disc and pad changes which pretty much makes my own jobs gratis
