i'd sit back on it for some time. it ends tomorrow around this time so if you watch the others that are bidding on it and watch it the last 10 minutes, that is when the most movement is seen.
I came late to this conversation and see price is up to $355. Also the sides are very low. If you want to haul anything loose you may have to fashion some sort of higher sides.
@Nyboy do you have a pic of your current trailer. if you aren't able to get this one on ebay we could give you some suggestions on how to add sides to the current one you own.
