I get constantly bombarded with this question from my wife.... I have no good answer. I just like assembling them, so each has a special meaning around a certain time in my life.... though I am running out of room on my AR shelf in my safe....
I have just the opposite problem, my wife seems to have confiscated mine for herself and she really wants purple furniture on it. So I actually need 2 more one for me and my daughter=4 (3+1 in 308) Oh the pain of not having the funds right now.
