I think what you did with posting the minimum bid 
amount on the page was good. that is how people 
will get their general price range. but beyond 
that, I like how ryen conducted her offer period -
 she accepted the highest offer and didn't post 
prices on her site. as much as I think you should 
get the most money for your cel, I also am 
confident you will cash in big time regardless of 
your method, and I'd be sad to see a bidding war 
that drives the price sky-high mostly out of 
competition. in any case it's your decision, 
sounds like the forum is divided on this issue.
