Sorry if these are stupid questions, I tried to do a search, as I'm sure it's probably been covered before... but I came up empty so I'll just ask. What is the pecking order of the Squier lineup of Strats? And what is the difference between an Affinity and a Bullet? Do they both have the thin body and narrow neck? Which one has the CBS style fat headstock? What is the cheapest Squier Strat that has "true" strat dimensions, as far as body thickness and necks?
