We're both making the same point, but you just look at it from a different point of view. You keep going on about doubling the cost of the rep, or whatever. I simply see it as an optional part of the cost. If you want to buy a rep as a toy that may or may not see the year out, get an Asian 21j. The movement can be replaced wholesale when it dies for about $30. It's a hassle to replace, but that's the hobby part if this obsession.
If you're buying a rep as a keeper, you need to factor in the cost of the first service. It's not a doubling of the price, it's just that you've only paid half of the price so far.
To imagine you're the sole crusader trying to teach us that the QC isn't there smacks a little of arrogance, especially when I can find dozens of posts a month from respected members stating this over and over, quite clearly.
You are not wrong in your views, but you're approaching them from a different perspective to most of us.
