toffeez, you don't have to post your answer on all the logs I am posting
I got your view clearly but was still trying to see if someone else might have something to share.
Anyhow, I found it, had to call a couple of old chaps and reminded me where to find what, so no worries. There are annual publications that have this purpose.
And yes, certainly what I am talking about is not the same as having a professional that makes a living keeping up to date data of every aircraft sitting across the table with you and helping you make a decision, but the data is there, and it helps forming a picture and narrowing down to a few candidate models.
Hoped to get some help here, guess thats not the spirit in this forum anymore.
