I recently bought the Leopold FC660M with Cherry blues. I really like it, because of the mostly standard layout and the dedicated arrow keys. I also use the other two "extra" keys (insert and delete), although I use delete more than insert. Of all the boards out there, the Leopold (FC660M and FC660C) seems to offer the best design in a nearly 60% layout with the addition of dedicated arrow keys. Its build quality is also top-notch. The only thing that bothers me is the rather unaesthetic asymmetry introduced by the overhanging arrow cluster and extra insert and delete keys. However, if you try to embed these in a purely 60% format, you necessarily disrupt the standard layout or you crowd the Fn layer.
The stock keycaps are PBT, but they are rather dark and not as legible as keycaps with a lighter background. Accordingly, I replaced the keycaps with gray and white dye sub PBT sets from Originative. I had previously replaced the keycaps on a Filco, which has costar stabilizers, but I had to use the Scotch tape workaround to get the stabilizer inserts to stay put in the stabilized keycaps. I actually prefer the feel of the Cherry stabilizers in the Leopold, and they were much easier to deal with when replacing keycaps. However, the Leopold uses non-standard spacing of the stems in the spacebar, and so I was not able to replace the spacebar; at present, this would require harvesting stems and using epoxy to cement them into place. I hope that Leopold might start using a standard spacebar or make its spacebars available in various colors.
Although I think that the FC660M (or the FC660C with Topre switches) might be the ideal board for me because of the dedicated arrow keys and its minimal and highly intuitive Fn layer, I am drawn to the even more compact and more symmetrical layout of 60% boards. For these reasons, I am considering getting a Filco Minila, Tex Beetle, or Poker. I like what I have read about the build quality of the Minila and Beetle, but the non-standard keys would make customization difficult. The Poker does not quite have the Fn layer I would prefer, but it has the most standard layout of all of the 60% boards and would be the easiest to customize with new keycaps.
