I bought this iphone 7 repair kit from amazon. https://www.amazon.com/Esdabem-Repair-Tool-Kit-iPhone/dp/B01LYBG861/ref=mp_s_a_1_3?crid=1O8F6TL9NBPN0&keywords=iphone+7+repair+tool+kit&qid=1553667693&s=gateway&sprefix=iphone+7+repa&sr=8-3
Has everything I need and drivers are actually pretty good. Probably done 100 screens with this kit. Only thing I have replaced is the black spudger because the tip wears down
I recently started using mobile defenders. Ive only ordered the Express ones, and the quality is good. What's probably helpful to you is the info on screen quality The cheap Amazon ones are like the Basic line. In my experience, they are also commonly not as bright, and sometimes don't fit super well.
Also, ifixit has a pretty nice repair kit for 30 bucks. I use an Amazon repair kit found here and it works good. Probably done 100 jobs with it and still fine.
If you want some of the really cheap single use stuff, send me a message and I'll mail them to you. I have a ton of them
