My fullfield II definitely has better glass than the 3200 Bushnell. In all fairness though I've only looked through the Elite scopes outside a store.
95% light transmission on the Burris. I've heard the Nikon is also very good for brightness.
Considering you can get a FFII 3-9x 40mm with Ballistic plex for $200 brand new, you can't really lose (PM me if you chose this scope. I'll tell you which store).
I haven't looked through the Nikon yet, although there have been a lot of very positive reviews.
You'll want to go check the three out at a shop first and then decide.
Any of these three will work. If I were to go for a middle priced scope I'd consider the Zeiss Conquest. If you were planning on going for the next level scope I'd consider doing it fairly soon. With the Canadian dollar taking a dive, it wouldn't surprise me to see the prices start climbing again. Get the old stock before the new stuff is repriced.
Let us know what you chose.
