wyflyer_55 - there is a link in the quick search box that will show you all items under $30. Go to the marketplace and click in a category. Then top right is quick search box that shows Under $30 items

rctrax - to filter a category when browsing as in your example click the subcategories at the left. when you click airplanes it shows you everything under airplanes including all subcategories. If for example you want to pare that down to just giants then click the giant link at the left. We call this our 'X-Ray technology". It allows you to browse through stuff at a high level or drill down to specifics so if your just "window shopping" or know exactly what you are looking for you can browse to it or use our powerful search.

Crashem - your post is still up there. Thank you for contributing to this thread in a constructive fashion.

visioneer_one - good idea. this is the stuff I'm reaching for here. A NIB filter would be helpful. I agree and it should be easy to add that.

rc_sport-RCU - if you list an item for sale you can check off "willing to trade" when listing it plus you can state in the ad title that you are willing to trade

easysport - see the first reply above in this post about $30. the link will show you all items in the marketplace under $30 instantly. this will get more sophisticated as we figure out if there is a better way to tackle it.
