2nd on the 'All' selection in the categories (and have it default to it as well) and text boxes for price ranges. But maybe you can have the ranges auto-populate and just give us the ability to define the range if need be. Also starting it off at zero kinda throws my reaction to the search results since at zero the results would most likely not show the product I was searching for and instead return accessories, etc. You might want to have the prices default at midrange.
Otherwise, loving the layout and simplicity. Ya'll rocked it!
We've been toying with this idea because of exactly the reason you mentioned. It's even worse if you search something and all the results are $0-$200 except for one that's $1000. We've also considered removing from the list the ones that are larger than a certain percentage of the average, to help keep the list more on target.
Can you please add an "All" for the category section? Sometimes I'd like to see all the results for a certain search term.
Instead of using the slider UI for the price range can we have text boxes, the slider is not very user-friendly when I am trying to pick a range of 0-300 when the whole range is 0-5000.
