Best Site for Large Quantity Whois Searches?

[barrysanders]

One way I contact potential buyers is through finding people/companies that have a site that is in the same niche. I do a lot of whois searching but I hate having to deal with captchas. Is there anyplace anyone could recommend where I could do a bulk whois search - so I have 100 domains I can list in one shot and get the whois emails returned?
