I wouldn't worry about getting one made by your mobo manufacturer. High quality components are high quality regardless of if they're made by the same people as made the motherboard. I've used both an Abit, an Asus, and an MSI, all in an Abit board. I personally like the MSI the best. It offers mutliplier and voltage tweaks just the like the others, it offers very good stability (which the MSI and ASUS did. Abit was a tad on the unstable side), and it sits on the slot a bit more securely than the Asus did for me.
