I honestly don't see anything special happening with this domain. It's hard when the domain is something like "HostPepper", only because the company that buys it would most likely have to use a pepper as their logo. It's like having a domain registrar named "BananaDomains.com" - it kind of limits itself.
I would say registration fee up to $25 tops.. Unless you can get a company looking for this exact domain, chances are you won't exceed $25 with a sale.
Just my honest opinion.
