Auctiva lets you save your listings (I have approx 15,000 saved and i think it is unlimited) You can also save a certain amount of photos. I'm on the basic tier & this lets me save around 8000 photos but with the higher tier packages you can save more. The basic subscription costs US$14.95 per month.

For me it is worth the money as I use my saved listings for every new thing I list.
