Regarding the redrafting vs. you get what you draft discussion, I'd say rare drafting is better for competitive groups (who prefeer to ignore the price of the cards they open), but keeping what you draft is substantially better for newer players. So far, I think I've played two or three drafts where we picked the rares in the end, and I'm happier with keeping what I draft.
It's true that adding the cost for a booster pack to the entry cost could be a bit annoying, but here in Argentina drafting is already expensive as is, and stores tend to have large profit margins from the boosters they sell, so they can add a booster pack per player (or every two players, most often) simply by charging a fraction of the pack's cost and aborbing the rest of its cost while still making out a profit.
In the end I din't go to the Gatecrash launch FNM because it was an unbearably hot night, but I'll try to play the Game Day. Gotta get my hands on that sexy Simic Guildmage (and perhaps the lightning helix angel).
