Since you have asked this question at the end of you other thread, I will simply copy and paste my answer here again
Think about it this way:
1. If you mod it up to US$500 You have a 99.9% close rep for about 1/6 th the price of a used PAM (they run roughly around US$3000 used).
My cutoff for the price of a rep is around 40% of the gen OR US$1000 whichever is less. Above that, might as well get a gen. Not to discount your assumption, but you will have to save on 5 or 6 US$500 reps to get a used gen PAM..
2. Subsequent mods have two possibilities:
- * If you can do it, great, then just wait for the new parts to arrive and bing badaboom done
* If you can't do it, you'll have to ship it somewhere, pay for shipping, wait for it to come back (boy.. not EZ).
3. Pre-mods are bigger in initial spending, but, hopefully there is little to no subsequent mods needed.
4. Think about your motivation re: getting a rep too. Is it to convince a scrutinizing AD? or is it to convince the general public? OR is it to convince you, that indeed, the watch is the real article.
99.99% of the time, the person looking at the watch is, well, YOU!
People don't care less, unless they're WISes, or an AD salesman trying to get a quick sale
My 2 cents
