Crucial has never failed me in 10 years. I have to say it sickens me how much cheaper RAM is compared to when I bought it 6 months ago!
 
Can I use 1333mhz RAM if my mid 2010 supports 1066? Reason I'd rather buy 1333 is, it's possible I'll get the new MBP sometime soon, and if I do, I'd rather have RAM that works well for both.
 
Anyone? I'm trying to pull the trigger tonight, so if I can opt for the 1333mhz RAM, I will!

No that RAM will NOT work, it will cause KP's. You should get the 1066 RAM specified for your machine! Buy the 1333 and you will be returning it shortly.
 
I'm looking to sell the 8GB PC3-8500 1067 Crucial memory kit I just bought about a month ago (switched from the 2010 to the 2011 MBP). If you're interested, shoot me a PM. I'm looking to get $70 for it.
