If you don't mind going just a little over $100 up to $115 this is a good board:
GIGABYTE GA-965P-S3 Socket T (LGA 775) Intel P965
Another option for <$100:
Foxconn P9657AA-8KS2H Socket T (LGA 775) Intel P965
There are some decent reviews on this board as well but it's not as popular as Gigabytes or Asus. If i get time to find the reviews, i'll post the sites here. Otherwise, it was either hardwarezone.com, overclockersonline.com or anandtech that had reviews on it.
You can find several on Newegg in the P945 and P965 flavor. If you plan on overclocking, you might want to adjust your budget though.
Edit: sillywabbit, here's review of the Foxconn P9657AA-8KS2H. You can definately trust the reviewer. It looks like it's weakness is the inability to adjust the CPU's multiplier which could suck for overclockers. However, there's been two BIOS updates since the review which may have added the feature. I'm not betting on it because I cannot find any info on what the BIOS updates entail but it would certainly be nice.
At $100 it would make a decent value OCg board with the ability to adjust multipliers.
BIOSTAR DUDE!, lowest failure rate per board manufactured, and it has the least extra BS on it. Windows will boot much faster without all that BS. Plus Biostar's performance T-forfce line has metal capacitors on it
But if you buy from Newegg PAY FOR FEDEX or they'll go gallagher on it.
