How to say "this" in "This is my third time in Taiwan"? Several times I've told people that I'm Taiwan for the third time and everybody understood me just fine, but I'm not sure I'm saying it right.

這個是我的三次在臺灣

I know 次 is the word for "time" in this sense, and I know it's also a counter word for times.

So is my choice correct for "this"? I said 這個 with the generic counter word, but should I really say 這次 since I'm discussing times, or is just plain 這 best?

Or should I really express it in an entirely different way?
You should say something like:


  這是我第三次到臺灣來
  
  This is my third time coming to Taiwan


You do not say「這個」, because the measure word (in this situation) for travelling/trips is「次」(which you've already said) and not「個」.
