Started with one 1/72 scale WWII Japanese tank, then a number of Type 97 variants, but has expanded into Soviet pre- and late war tanks, and starting to look at German assault guns.
Fortunately they’re smallish, so storing/displaying them is not (yet) a problem.
But I probably don’t need to acquire more kits just now. 
Ahh,you’ll get over that feeling,it will pass,and before you know it 
That looks like a 401(k) worth!
Whoa! My stash isn’t that big but I’m in a similar situation, Jon. I’m buying new kits faster than I can put them out. And I’m running out of room to display them! I’ll probably see about giving away or selling some of my not-so-good work eventually, and keep the best.
Get down from there - do NOT crush the boxes!!
I’ll tell you what doesn’t help is PayPal pay in 3, it’s far too easy just to add kits to your basket and only pay a lower amount and worry about it next month.
I started on 1 1/72 Eduard Hellcat and now have 16 kits + extras and paints in less than a couple of months.
It’s an illness that has no cure 
I doubt many here need to acquire more kits. But don’t you want to acquire more kits? 
Yeah, I just ordered again. But it was a good price, etc.
