If you like the look of stainless, and plan to keep it clean, then sure consider it.
Seen one before at retired guy's house selling stuff on CL. He had it pretty well loaded up and had no complaints, but was light use DIY as he wasn't opening & closing every day. I tried to get him to sell with "sweeten the pot" deal of bunch of Craftsman items. He would not sell it.
Not many choices for that stainless look, so your call on what you'll spend. If you love it, then $1,000 to $1,200 may work since it's damaged. However, if you're mostly needing a double-stack for heavy toolbox access everyday, then maybe $800 or less should be your cutoff as $1500 to $1800 could get you used truck brand painted tool box if you really hawk CL.
Good luck with your decision.
