how muchinber could still sell for more than inkon .... but anyways I can't say I like either one of the domains ....
In that case, you should list it on some brandable domain marketplace like sh, bp, bb.inkon.com looks like a great premium domain. Registered in 31 tlds, 17 years old, 5 letters 2 words - I'd be looking for a lot of money if I had this to sell.
inber.com not quite so good but I'd still be treating it as a decent premium domain name.
