Assuming you are able to get some $$$ out of Hastings, this is sort of a tough decision. You say you don't care about debt, but unless you have a rich uncle who is literally sitting there waiting to pay your loans when you graduate, then there is no question you care about the debt.
Transferring schools in the same market can be a little harder to justify than transferring to a school in another market that you want to work in. Presumably there will be some overlap between the firms that come to Hastings to recruit and those that go to Stanford/Boalt, and thus there will be some overlap of firms you would like to work for. If the firms you want to work for are already coming to your current school, then why transfer?
Oh, at this point I should mention that in my experience I don't think transfers receive much of a bump in the recruiting process by suddenly becoming a Stanford/Boalt student. If a firm wouldn't have hired you as 10% at Hastings, they most likely aren't going to hire you as a Boalt transfer whose grades were 10% at Hastings. Reasonable people may disagree about this, but that's just my thought and I think it is rooted in some common sense. One of the bumps you MAY get is it shows a desire to work in a certain market (say, if you go from BU to Chicago because you want to work in Chicago, that will show commitment to the Chicago market), but that won't apply to you because you are transferring within a market (so to speak, I understand CA is big).
Anyway, so why transfer then? It becomes all about access. Are you going to be able to interview with significantly more firms that you want to work for by transferring? What is the OCI process like at Stanford/Boalt? 100% lottery? How many firms do students there typically interview with? Ditto for Hastings. How many more firms are going to recruiting at Stanford/Boalt than at Hastings? Which firms? Are those firms ones you would have a shot at anyway? Important to remember is that you can always mass mail the firms that aren't going to be at Hastings for OCI. You would probably end up doing this at Boalt/Stanford anyway, since you aren't going to get EVERY firm you want through OCI and the ones you don't get you will mass mail (in which case you have the same access you would have if you hadn't transferred). Only now when you mass mail as a transfer, you likely won't get to add law review to your resume.
This is a long ass post and so I'm going to stop for now but what I guess I'm getting at is that there is a sense around here that transferring is almost always a good decision. When you are talking about increasing your debt load but 75-100k, though, it is almost never an easy decision and I tend to think more people in that position should stay than go. You give up a lot when you transfer, and even if you end up at a great school, you could still strike out at OCI. Trust me, life is all rainbows and gumdrops before OCI when you are sitting at 5-10% from a decent school, whether you end up transferring or not. I was there, and I thought everything would be fine no matter what I did, but once OCI starts rolling and you begin to struggle, things look a lot worse in a hurry. All of a sudden you feel like you might as well have finished in the bottom 10%, because the result is going to be the same - OCI strikeout. Granted, this wouldn't be fun no matter what school you are at, but it's A LOT worse when you feel like you gave up a significant amount of money, law review, etc. for nothing.
But you are a 1L, so don't even worry about this stuff until you finished your first year.
