Or did I get ripped off?
There's no objective way to determine that. Assuming you get the cards (which seems likely), and you really want them, and you were willing to spend 500 dollars to get them, then no, you were not ripped off. How much anyone else would have payed for them is largely irrelevant.
Buit that's not what you want to know now, is it? OK, here's the thing. I did the math, and if you weer to buy that whole deck from, say, Trollandtoad, it'd cost you exactly 1278 dollars and 11 cents. But you coudn't, because there's several cards in there they don't have in stock, namely:
- All Hallow’s Eve (1st place radiant ’98)
- Baron Sengir (1st place Spring ’98)
- Black Lotus (1996)
- Blinking Spirit (1st Place Winter ’97)
- disenchant (Radiant ’98)
- Fallen Angel (4th place Summer ’97)
- Guardian Beast (4th place Autumn ‘97)
- Incinerate (2nd place Radiant ’98)
- Juzam Djinn (Duelist 1996)
- Karplusan Forest (98)
- Nether Shadow (4th place Tempest ’98)
- PyroBlast (3rd place Harvest ’98)
- Swords to Plowshares (3rd Place Radiant 98)
- Wheel of Fortune (2nd place Radiant’97)
...or 548 dollars and 5 cents out of the 1278 dollars and 11 cents. That means over at T&T, you'd pay 730 bucks for fewer cards. So yeah, it seems to be a decent deal.
By the way, it's an illegal deck because it has 5x BrushlandÂ
