Mark, I have yet to see an Ext just an extra couple bucks more than an INT. Its usally ridiculous and for what? Never understood the extra cost of a EXt. Plus there is no real data to prove a Ext is better, or did i miss that?
I understand what you are saying Davey, But if in my insump skimmer cost $999 and my external in $1199=$1299 range, percentages are under 25% and that means "a few more bucks". I did not right a direct dollar amount, but for the BK deluxe it is a couple hundred more. By the time I take the loss on the first, it would of been better to spend the extra couple bucks the first time around.
As for in sump vs external and which one is better, I will take the external because of the extra contact time any day of the week. There are no quantitative data that measure this (yet

If an external takes 20-30 minutes to recover and the external takes over an hour, doesn't that exhibit, just a tad, which one is out performing. That is one of the most crucial times when we need our skimmers and an internal is basically saying, "I'll get around to it sooner or later"
I have a separate compartment for my skimmer, but because of my water volume, it needs a place to go if the pump turns off. You don't think there is some reasoning behind +/- 95% of larger volume tank owners run an external model skimmer.
These debates are a lot of fun and as Terry and I have talked about, it also has something to do with what we want vs. need. I have always ran in sump skimmers and I am glad people around here started showing me , IME, a better way.
