I think that's a good buy. This is a very quality typo of anime, and anime gets huge searches. Looks like amime might get some decent traffic by itself, my guess is you'll get between 800 - 1500 type-ins per month, which is very very good, especially with a word like this that is extremely easy to monetize. And if you were to develop the site rather than park it, and optimize it well for both anime and amime searches, I think you can get it very near front on the search page results, and then ads/adsense might make you more than parking revenue.
I think you paid a very good reseller's price for the name; based on guessing the traffic, without being given stats, I'd say your price was not low but not overly high either, kind of in the good, balanced 'sweet spot' where both you and the seller are happy and neither of you got ripped off. Let us know how the traffic does.
