Little use for a past tense auction domain to be honest. What would a potential developer do with it? The .biz extension also lets it down, however, it is slightly appropriate for this name. It is not a catchy term, it sounds drab IMO. All the other main extensions are taken, however, I cannot see this domain amounting more than low - mid xx. Good luck with it.
i, unfortunately think regfee - the .biz ext hurts - also the name cannot be very useful, the only use for a past tense in this case it to list already sold names which can be used for less than would an active tense of the word
