eBay is a good place to set this type of business up. Just beware the fees! If you are planning on having a larger selection, it is sometimes more useful to set up a "eBay Store", where you pay $29.95 a month, and avoid a lot of the listing fees.
I am currently on eBay, but I don`t tend to do much with it. I have thought about using it to open a store, but am still working on crunching some of the numbers to see how useful it would be with the concept I have. It`s amazing how many people are CONSTANTLY buying things via eBay... in fact, according to the last numbers I`ve seen, eBay is the second to third most used commerce suite online (based on where you research the information from).
I believe that you might like setting up the store, then "blasting" the site via marketing across a wide array of websites/search engines, depending on your marketing allowance.
I hope this helps!
