Are there any good search engine traffic estimators out there similar to Google's Adwords Traffic Estimator

Question

It can be online or desktop software but I have around 400 keywords and I need estimates for at least Google and maybe Yahoo and MSN if available. I can't use Googles, I put all the keywords in and it spit out that I had some bad keywords but didn't tell me which and I don't have time to go through every single one and troubleshoot the issue.
