smaratacaiberry.com is probably a good name if you want to promote acaiberry products. It's not really a well-known name other than for super health enthusiasts, and the name is a bit difficult to read or write if one is unfamiliar with the product. But if you don't develop it, it's no value in my opinion. Here is a cached screenshot of how it looked a couple of weeks ago: Is Acai Berry a natural weight loss solution? | Smart Acai Berry
Automotive.nu is quite good as well. Normally, such domains aren't as good as the big three, but .nu has been around for quite awhile and is probably a good sleeper for gems like Automotive.
If you can develop automotive.nu, perhaps mid to high $$$, or even more if you can convince one of the big three to take it off yoru hands for a good price.
