Pre-registering was $60
Air was $15
Paint at $75/case. With a Resurrection, you could be looking at anything between one and eight cases, depending on how crazy you wanted to be. Figure two or three to be sensible yet covered - I shot a 240 round Z2 plus something like 9 pods during the final battle with my Resurrection.
If you figure $300, plus your travel expenses, food, and whatever you're going to spend at the vendor areas (and whatever you think that will be, at least double it!), you should be good to go.
