No buddy, u r not getting my point, I am not saying that IAF shouldn't go for foreign fighters & induct only tejas, i am saying that if IAF is going for FGFA/Super Sukhois/Rafales but should not forget the tejas since it is a single engine, decent, 4th gen, economical fighter that India can mass produce, without relying too much on any foreign nation. If IAF can go for 600+ foreign fighters, than i don't think they should have problem in inducting 150+ homegrown ac since money is of course not an issue.
As far as sophistication of any ac is concerned, it's the question as to how one sees it, no one is saying that tejas is better than rafale, but we have to keep in mind that they were developed to replace migs & become a low end fighter of IAF, obviously u agree that tejas are many times better than notorious flying coffins, so why not induct them in parallel to the inductions of world's best jets.
