The yellow keys and black body? I have one with blue switches and I have two ninjas, one with browns and the other has black switches. They all are without the ten key.
What do you want to know? The yellow/black Filcos actually look pretty good. Of all my keyboards I've used at work it's gotten the most attention, for obvious reasons, and a few people have wanted one. It sits right next to my ninja with browns and no one makes comments on it. It's too stealthy to get noticed.
The key caps feel different. The yellow ones feel more textured than other Filco key caps. Not rough, just not a smooth/silky, I'd almost say like it has a slight rubber coating on it (but it doesn't),
I own seven Filco keyboards. What it'll come down to is if you like the color scheme well enough. I have a pink and white Filco and I really like it too.
