Never thought I'd say this, but I'd get a Leopold over a Filco if you're getting a brown. I actually like the way my Leopold feels over my Filco with browns. The keys feel a little nicer, maybe because it's otaku, and the switches feel a little smoother. The later part doesn't make sense to me, since they are both cherry browns. For $30, not sure if a Filco is worth it over the Leopold.
I use the otaku at work and it causes problems when other people need to use my workstation. So I ordered a normal Leopold with browns, and I'll swap them out quickly when I need to (take advantage of the USB cable). Plus you can never have too many keyboards. I'll have 3 at work after this.
The stabilizers aren't as nice as the ones on the Filco but I don't think you'll notice if you've never used a Filco before.
