Thanks to everyone for your feedback. I especially want to thank those that came to my defense in posting this question. As I stated in my initial post, previous threads on this topic were closed and outdated. We all know that when it comes to international travel, things can change rapidly, so I wanted more current opinions and information.
I am a bit of a research geek and am in the domestic tourism business, so I have done a lot of homework in addition to the responses posted here. Here is a summary of my findings.
In my town, I have contacted every bank and credit union and all charge for foreign transactions when using an ATM card (I do not use debit cards ever due to the inherent security issues with those). It appears that the banks in Italy (or any country) establish their own exchange rates and rarely strictly use the prevailing rate (found on OANDA.com). So, when I use an ATM card there, I will be paying a fee per transaction (flat $3 from PNC bank plus any fees the local bank may charge for ATM use) and exchange rate will be that particular bank's prevailing rate. In my area, via AAA and PNC bank, no fees are charged for foreign currency exchange, however, the exchange rates at both is predictably lower than what is found on OANDA. For example, per OANDA, for $200 US dollars today (the minimum to avoid a fee at AAA), I would get 181.68 Euros (rate has been on steady incline again in recent days after a huge decline in early Feb.) However, on Wells Fargo, that $200 would get me just 172.33 Euros. Obviously that $9 difference is more than my $3 transaction fee, but I have no idea what a bank in Italy's exchange rate will be that day.
For my purposes, I am keeping an eye on the Euro/US dollar strengths. If the dollar starts to decline again, then I may order Euros here as I will get a better exchange rate than if I wait and I won't have to immediately look for a bank ATM that is in my network upon arrival.
So, the answer isn't as simple as some seem to think, as it isn't simply about fees. If the dollar tanks in value as it did a few weeks ago -- as compared to the Euro -- I will have been better off to do my exchange now, rather than waiting.
