Best place to buy OWC RAM

I want to max out my MacBook to 3GB.
Is this the best and only place to purchase the OCW 3GB kit?

Thanks.

That's the ONLY place to purchase OWC RAM. You could also go to one of the following sites:
www.newegg.com
www.frys.com

And find single 1GB and 2GB sticks of PC5300 (or 5400, they're the same thing) 667MHz DDR2 SODIMMs (obviously the same manufacturer and series) from Crucial, Kingston, Corsair, OCZ, Mushkin or Patriot, but it might be cheaper to get the OWC RAM. You'd have to compare the prices.
