The fact that they're subsidizing the tool kits (the $1200 deposit they take is nowhere near the value of all that equipment) also suggests that they wanted regular people to get their hands on these tools (and no doubt talk about it) as opposed to charging the actual market value which - while affordable for a repair shop - would've been way out of reach of a regular user.
After all, this kind of equipment is not new and has been available for ages (comments on another thread about this say that in China every phone repair outlet had similar equipment) if you could justify buying it, and yet we haven't had articles like this on major tech news websites until Apple subsidized it enough and put it in a nice, idiot-friendly package.
