But for us budget minded, cheapskates, Motul 600 is probably more widely used.

I used to like Motul 600 a lot for track and other heavy-duty driving - but unless you're really dedicated to changing it often (as we do on the track), it can cause some problems with corrosion since it absorbs a lot of water. I let it go for a full year once and it came out looking like crap...

For street use, the one I liked a lot (before they discontinued it) was Valvoline SynPower DOT4. It was dirt cheap, and the dry/wet boiling points were more than anyone would generally need on the street (and some track use). I'm looking for a good replacement now, and the ATE fluids look nice. You can get the same fluid in Blue and Amber colors, which makes it really easy to properly bleed the system - once it changes color, you know you're done.

Brake Fluid

Here is comparison of the latest specs:

Brand ------------ Dry/Wet - Price
Valvoline -------- 480°F/311°F $5
CastrolGT-LMA - 509°F/311°F $5
ATE SuperBlue - 536°F/388°F $15
Motul RBF 600 - 593°F/420°F $15
Motul RBF 660 - 617°F/399°F $30
Castrol SRF ---- 590°F/518°F $80

I use GTLMA and flush twice a year with very agressive backroad riding and a couple track days & autocrossing.
I do threshold brake frequently and havnt boiled my fluid yet, so for now with my current stockish setup im fine with the cheap stuff.
So if all you do is cruise around and dragrace then the cheap stuff should be fine for you as well

They discontinued the Valvoline? This must have been recent, as I just put it in my car in May.

I changed to the Castrol GT-LMA when I had the clutch issue and the belangers still cooked it (no difference than the stock fluid)....with the Castrol SRF the issue went away...yes its 75 dollars but its spec'd to absorb less water. I understand Motul 600 needs to be changed more often so I spent alittle more,but results have proven satisfactoy....
