If you street drive, figure you'll be halfway to the wet bp point within about 3 months, and nearly completely there at around 12-18 months. If you have a track day, figure you'll be nearly at the wet bp by the next morning.

For lazy street cars, I'd recommend The Castrol GT LMA. It's getting a good reputation and is quite cheap and long lasting.

If you've experienced substantial or recurring brake fade or pedal slush with your OEM fluid, but still generally keep to the street, I'd have to recommend the ATE Super Blue (also called ATE TYP 200 - exact same thing, but amber instead of blue). Incredible performance for the price, and you'll probably only need to change it every other year or so.

If you want track days, you'll be changing the fluid a LOT - like every morning of every track day. The Ford Heavy Duty Fluid is a great trick for that - very cheap and a very high dry bp, but don't expect it to last much more than a day. If you need a touch more dry bp or a longer life, you can jump up to the AP 600, Motul 600 or the NEO 610. Much more expensive, but all have really great performance.

If you are rich and absolutely must have the best. Castrol SRF. Nothing else comes close. Don't look for it in your average store, but they do retail it. Check the net.

One more important note -> ALWAYS buy brake fluid in a metal can, never plastic. Plastic will allow the fluid to absorb water while just sitting on the shelf (sometimes quite slowly, but how do you know how long it's been there?).
