AC/DC easily the most expensive and not surprisingly.
Yeah, I remember seeing them for the "Stiff Upper Lip" tour (which I believe I've probably spoken to you about a time or two before) along with maybe Van Halen, Creed, Def Leppard, Matchbox 20 and the Ozzfest being some high cost Arena (or close to it) shows just as well. I probably could've and did see around 5 or so close/personal club type Concerts for the price of one of those seats. Those club seats included great Artists that I've seen including Ted Nugent (2 times), the Foo Fighters quite a few times, Needtobreathe, Opeth, Fuel, Nickelback, Sevendust, Jerry Cantrell/Alice In Chains alongside many others.
Going along with all of that, I wish that I had the chance to see Alice In Chains (with Layne), Nirvana, Type O Negative, INXS, AC/DC (with Bon Scott), Dio and the Beatles, etc... I did get to see Pantera, so I didn't miss out on that. Artists that I haven't seen yet and/or very much desire to see again include Neil Young & Crazy Horse (above all), Megadeth (with Nick Menza and Marty Friedman), Metallica (back with Jason Newsted), Rush, Alice Cooper, Kiss (in the original lineup) and Aerosmith. That about sums Concert experiences up for me.
