I ordered all of my woodenware from Bee Thinking. I got all medium, 8-frame boxes, Western Red Cedar, as shown in this thread. http://www.beesource.com/forums/show...ed-Cedar-Hives
The complete hives came with three medium boxes, I ordered two extra each (excess of optimism for a first year. Yeah, I do that.) Also got enough frames to fill the entire mess o' boxes, SBB, and entrance reducers.
Of course I paid a fair bit more than if I had ordered commercial grade pine boxes, but it was worth every penny to me. The boxes are more beautiful in real life than they were on the website, and very well made. The communication was clear and fast, the shipping took a little while - a little over two weeks from order to delivery, not actually too bad at all - but I didn't mind because I was not in a hurry, and the shipping was free.
Their foundationless frames have a built-in comb guide. I'll come back and say more about how they work once there are actual bees in the boxes sticking wax in, but it certainly "looks" (from what little I know, aka nothing) like it ought to work at least as well as popsicle sticks or cleats nailed up sideways.
There's pictures of the assembled hives on my dining room table viewable on my Tumblr, linked in signature block, if you want to see them.
Overall I am very pleased with this company and will order more from them in the future if I decide to add more hives.
