I used to like detolfs, but there are a couple of problems ive noticed. 1. unless you have it on a riser, that bottom shelf is basically worthless. 2. i do this, and I've seen a lot of others do this, but we tend to jam multiple figures on each shelf and when you do that it looks like a mess, especially when there are figures behind figures. I'm also not sure about putting a lot of weight on those glass shelves, thats why my diecast iron man is on the bottom.
I've come up with a partial solution, legends display cases. they are pretty slick for 80 bucks for the 1/4 scale (hulk and thanos fit in this), and i think the 1/6 is 60 or so. when i get those coupon codes from sideshow thats what I'm ordering since to be eligible the item has to be 50 bucks.
None of these hot toys figures will trouble a detolf shelf. Even if you squeeze as much as can fit on a shelf.
