I had a domain that received about 700 type-ins a month. I sold it for $400. 1,000 type-ins? I think you could nail quite a bit... depending on the domain. If you had a domain from a saturated market, it'll sell for more. For example: Assuming donains.com got 1,000 type-ins, it'd be worth quite a bit because of the niche. If you had computrs.com that had 1,000 type-ins, the latter domain would sell for more because computers are far bigger a niche than domains, thus the traffic would be worth more.
