So far, everyone I've handed one of these keyboards to loves it. I've converted my entire lab over to these things, as well as my SO, 2 of my close friends, and most of my family.
These are all people who are of the opinion that "it's just a keyboard". Until I let them try my customizer. Then they change their tune. Personally, I don't see how you can wrong, unless you like a light switch.
And if you do like light switches, just suck up the cost and get a topre. Should last nearly as long as the customizer, if not longer (read: long enough that it would be dollars per month of ownership, likely).
I guess it comes down to, how much do you type in a given day, is your keyboard a pivotal part of your work experience, and how much do you value the feel of the keyboard?
A customizer is an excellent choice, especially if you prefer click, or don't want to spend the money to get a realforce. If you prefer quiet, and money isn't an issue, get the realforce from
The Keyboard Company.
In either case, it is money well spent, if only to know your keyboard won't crap out in 6 months to a year.
And yes, I have a bias towards both of these types of keyboards. I dislike the cherry switches. But, as I've said, everyone I've introduced to the Customizer loves it, and ends up with one. Though two people have snagged happy hacker keyboards instead (topre switches).
