Also watch out for the Southbridge chip number, you want a SB700, not the older SB600 that is present on the early AMD boards
I run the MSI K9A2 Plat - http://www.overclockers.co.uk/showproduct.php?prodid=MB-093-MS&groupid=701&catid=5&subcat=808
No complaints here, runs very cool, overclocks very well and is full of excellent features including exceptionally good voltage control and quad fire graphics.
Is AM2+ motherboard CPU fitting screw in?
