None of those are encouraging signs. I find it pretty amazing that people still choose to consider sites that offer no clue as to who's behind it, not that I'm saying that about the OP. It's up to the site operators to attempt to earn some trust and even then I'd want major track record to even dream of it.
I agree it doesn't look good. I wouldn't ever consider buying anything especially bitcoin hardware related from a whois protected domain. If a company is legit they should have the relevant information public and that should tally up with other publically available information.
Companies that go out of their way to hide this information are normally up to no good.
