I just redid my Transformers shelves. I ditched the old Detolfs and made use of some Ikea Billy Bookcases and then customized them to fit my collection. In addition to my Transformers, I have a variety of other lines in my Man Cave, including a large collection of Hot Toys, Legos and Voltron: Regarding the custom Billy Bookcases, I figured I'd share what I did: 1. Started with 1 large and 2 small Billy Bookcases, and staggered shelves based on my intended setup 2. Prewired all the shelves with 4 sets of this LED Light kit from Amazon 3. Set up all light strips as far to the front of the shelves as possible 4. Added thin shelf planks to block the light bleeding, as well as floor and crown molding 5. Closed up the gaps in between shelves with same thin planking 6. Caulked, primed and painted to match existing molding in my room I wound up going this route after struggling with finding the right glass cabinet to house my collection. Detolfs were great for awhile, but I wanted something more unified without having to keep adding more cabinets. I also looked into a giant glass cabinet/curio cabinet, but costs were so high that I was turned off by that route. All in, this custom bookshelf cost me $150 from Ikea, $100 for the lights, and $75 in wood. Hope you enjoy!
