I never owned any artisan caps besides gas masks and a hellboy, but I find the Checkey to be a nice entry point. Aesthetically, I find it looks great on IBM boards, and it practically shines when compared to my gray desk and my SSK. Although the keycap isn't made of metal, the metallic look has always been a thing for me ever since I got my hands on metal-backed keyboards such as the Zenith ZKB2R and Omnikey keyboard.
Since my purchase of my SSK back in February, I noticed I have been using the keyboard quite a lot. This is surprising for me because I've always known myself to use my Topre boards the most. I think the reason I've been using my SSK so much is because it's the only clicky keyboard I own that truly satisfies me when my keyboard rotation calls for it. Personally, I think good artisan keycaps are what make me use certain boards more. I almost always slap on my ruby red gasmask and hellboy Topre keycaps when I begin to use my Topre boards because I love the subtle addition of color and craftsmanship it adds to the overall premium quality of the boards. Of course, the SSK is no exception to the quality I look for when adding artisan keycaps.
I don't think I have the great amount of passion, such as Karura's efforts to create a retro-pc specifically for his SSK, to utilize the Checkey. However, like many of the users who made the effort to test their luck, I just wanted to communicate my interest and appreciation for the Checkey.
Here is an old pic of my SSK:

Thanks for giving users the chance to own the Checkey. As a person who purchases personal archival prints, I know it's not easy to let go of them when you think it can go in better hands. I purchased quite a few prints that never quite worked well in my rooms, and so they often become gifts to my friends and family who share similar tastes.
