After some research, as extensive as possible solely online, and aided by [thefind.com][1], I settled on these sets (click to go to the online store):

<a href="http://www.thechesspiece.com/proddetail.asp?prod=G-5LQ-DRW"><img src="https://i.sstatic.net/88iBy.jpg" width="256"></a>

Both are magnetic, and are alleged to have strong magnets.

The first is a mere 7.5" board, but it doesn't fold (which I like), and it has a drawer (meaning that I can set up and tear down without pouring pieces all over the place or even move the board).  The price: $29.99.

I went for size with the other: a folding board, since the price was much lower for a folding board of that size (12") than for a board with a drawer.  This one costs $39.99.  

They have a claimed retail price of $79.99 each, which seems a bit exaggerated to me after seeing other stores' prices for similar sets.  I would place the value around $50 for each based on other prices.

I considered buying their [12" drawer set][3] ($79.00) in lieu of both the above, but decided against it, since it would end up costing more, and at this point I would rather have two sets.

Another set I was seriously considering is sold by another store.

I like this idea, since not only does it have a handy place for captured pieces to go, it also can be closed up in a certain position to be played later.

I'll update later on how the ones I purchased turn out.

**Edit, a week later:** I've just received the sets, and though one was not the exact set I ordered (hinged w/ board on top instead of a drawer), the sales rep I contacted is going to initiate an exchange shortly.  The other set was better than my expectation, with smoothly finished wooden board and pieces, and inlaid wood squares.  No magnets are visible, and the pieces fit snugly in the carved felt inside the box.  It's a handsome size and convincing weight, and the pieces are the same.  I believe I would have paid more for it.

My review of the other set will have to wait until it arrives...
