Well, it would be easier for me to take a pick than try and count them,also,as has been said,do you just include AFVs, figures,Dio sets, accessories sets?.... It's a hill of beans really.
I'm with Dave and Tim mind, DON'T feel guilty of whatever you've amassed,or not! AND flitting around due to the "Shiny" syndrome is totally acceptable,(but I would say that wouldn't I ?!

)
I no longer smoke, don't go out much,and basically work 5/6 days a week for an average 9 HR day...
..... So WHY shouldn't I buy kits too regularly,that I'll probably never get to build....
..... It's my main interest outside of real life... And I love just looking at the boxes sometimes!!!
