Just want to know if you've experienced anything good / bad from these other guys (we already know enough of OWC). The prices below are for a 4x2GB kit. memoryamerica $346 http://store.memoryamerica.com/fully-buffered-pc6400-ddr2-ecc-8gb-apple-kit.html dms $356 http://www.datamemorysystems.com/_apple_info/Apple_Mac_Pro_Quad_Core_8_Xeon_2.8GHz_Memory_1487.asp Transintl $368 https://www.transintl.com/store/category.cfm?Category=2726&RequestTimeOut=500 and owc $379 http://eshop.macsales.com/shop/memory/Mac-Pro-Memory Also, if you find some other reliable sources, please provide a link / or part description ("I got a good deal from Newegg," doesn't help a whole lot) A few dollars may not make a difference to some, but the point is, a healthy competition will keep the prices down.
