Rather than "bumping" your ad repeatedly, which does more to annoy people than sell your item, why not try adding more information or better photos to sell the camera, or images you've made with this system?
Everyone deserves a fair opportunity to advertise their item, and repeated "bumping" pushes other items down the list. It hasn't been enough of a problem that we've had to make a specific rule about it, but this is the kind of thread that draws a lot of complaints.
fair enough, I will update the ad when i get a chance. Is there a way to delete threads? I'd rather post it as a new thread at some point, but don't want to disrupt the listing more than i may already have done.
You can use the "Administrative" tab at the top of the thread to the right to close it, and you can just report your own thread using the button that looks like a triangle with an exclamation point asking to delete it, and one of the moderators can delete it for you.
More expensive items like this can take a while to sell, unless it's something rare and in high demand.
