Should I keep my Justice League figures?

I am contemplating whether to give up my Justice League toys collection.  I only collect the 4.5-inch Justice League action figures that are based on the Justice League animated series.  I started collecting them when I got hooked on the cartoon series a few years ago.  I told myself back then that I would only collect the core 7 members of the Justice League team.

Then came the Justice League Unlimited animated series, which introduced an army of new Justice League members to the team and to the toy line.  As such, I gave in to my weak emotions and started to collect a number of the other spupporting Justice League characters.  I now have around 40 figures, both loose and MOC ones!

Last month, I took out my entire Justice League toys collection to take their photos and I even created a webpage to put them all up for sale.  I have not uploaded that webpage because I thought that I would postpone my decision till after Chinese New Year.  Furthermore just before Chinese New Year, I managed to complete my Justice Lords team by chance.  Now that the 15 days of Chinese New Year is coming to an end on this Thursday, I have to make the decision again. 

Should I just keep the core 7 members of the Justice League and Justice Lords team; and let go the rest of the ‘minor’ and variant characters?  Or should I just let the  entire lot go, together with their DVDs and VCDs?  Or maybe I should just keep them all, since there are just around 40 figures that do not really take up that much space in my room, compared to my larger toys such as My Little Pony.  I am not exactly helping myself make the decision by continuing to catch the Justice League cartoon on TV every evening,  This is really, really a dilemma.
