What I find interesting is you seem to have had mainly different bidders each time. Lots of bids but basically only a handful of bidders each time.
You can, I think, make a second chance offer to whoever was your second highest bidder.
Whether that will end in a sale though I am not sure because from what i can see, most of the bidders this time around don't have a high number of feedback & now they have had a chance to cool off, they may feel that if the highest bidder bowed out, then maybe it was overpriced or there was something wrong etc
You're starting your bids at $99. I presume then you are happy to sell at that price & anything else is a bonus.
Given that both auctions have reached the $225-$255 mark (but haven't actually sold, remember that) why not do as twyngwyn suggested and just skip the auction format and advertise at a set buy it now price (you could add, or near offer) and list at say, $235.
That way, buyers know where they stand and can think about it instead of getting carried away in the moment and then rethinking it after the sale.
