The problem with bluray domains is half our hyphenated and half are not, which lowers the whole market of blueray domains. Add in the fact that many domains are blueray to try to pick up on misspellings.
Blu-ray domains with a hyphen arn't going to be worth very much IMO. Internet users are used to seeing hyphens as a poor quality domain... and with multiple words the hyphen just looks awkward.
I believe its worth reg fee, but you may be able to get up to $20 on ebay.
