Ok I went on a Google trip today and found lots of examples of people who have raised their Detolfs. Here are my findings thus far...
Group Displays
Apparently 3 Detolfs fit on the IKEA Lack TV stand. The good news is that by buying an IKEA product, the color wood will match your Detolf perfectly. The bad news is that as you can see, the Lack is starting to bow in the middle. As the original poster said, "I added some reinforcement!! This pic is old."
According to IKEA, the Lack can support weight up to 143lb/65kg. Three Detolfs total 267lb/121.2kg plus what's inside.
I love the fact the Lack is only $49.99 and I love the fact the wood color will match the Detolfs. My only grumbles are 1.) I wish it held four Detolfs, not three. 2.) No matter if he held three or four, I wish it was sized to fit them better 3.) I'd be scared that I wasn't reinforcing it properly and they would all come crashing down.
If you like military memorabilia, check out this link. He has a cool collection. As for the Detolf risers, he apparently had a custom bookcase built to perfectly fit 4 Detolfs. Total cost? $400 for materials plus $500 for labor. Ouch. Looks awesome, but way out of my ballpark.
This one looks great. The wood matches the Detolf close enough, and it just about perfectly fits 4. I wish I knew where he got it from, and if it comes in a darker color as I have the black-brown Detolfs.
Another custom case, this one perfectly sized to fit two Detolfs across and DVD storage high.
Last, but certainly not least. My absolute favorite of the group displays from what I found. It's a custom riser that fits 4 Detolfs perfectly, and pretty much matches the wood as far as I can tell. The best part to me are the drawers. I could hide extra clothes, accessories, and heads in there. Argh, I want this.
Single Displays
This is the only example I could find of risers on a per case basis, and they look awesome! They fit the Detolf, they look sturdy, and the wood color matches! These are the property of Paul Kaiju from an event he did in NYC in 2008. I don't know where he got them from. He actually has a blog I found.
