The prices are reasonable if you order them off Ticketmaster when they FIRST go on scale. I got the pre-sale password, and had my choice of levels to buy from. If I remember correctly, they were like: $85, $125, $200, $300, $400, $500... and than I stopped considering. I bought 2 tickets at the $300 price range, and I've got floor seats. They aren't ringside mind you - but on the floor nonetheless.
If you try and buy Wrestlemania tickets a few months after they go on sale, things are going to get ugly for the wallet quick. Ticket sites make a living off ordering bulk tickets for events, than jacking the prices and selling to the poor folks who missed out when they went on sale.
If you want to buy tix, just keep an eye out on sites like this - they announced 4 or 5 different pre-sale passcodes weeks in advance.
