There were a bunch of stores I found with Red Cherries. I think I also found one with an ANSI layout.
I also tried a full 55g Realforce keyboard, I may consider it in the future.
Seeing as I was able to try ALP, Black/Brown/Blue/Red Cherries and Topres on this trip, I think I was successful in terms of keyboards. Once I have some spare cash I'll probably be able to decide on another keyboard.
I did pick up a Slimblade trackball, as out of the ones I saw, it had the best build quality.
So far in using it, its been awesome. I haven't used a trackball since 1996. Though its going to be a while until I unconsciously say "Slimblade" instead of "Slimeball" when reading the name quickly.
ripster, the pictures are
here, as per my like in the opening post.
This is one store you'll want to go to ripster:
There are 3 different shops with the same name. This one just has keyboards and mice. This one definitely has the most keyboards on display. Though Yodabashi has a larger selection of try-out mice (its the stupidly huge department store in Akihabara, with mostly electronic stuff).
I was disappointed that I didn't find many older keyboards (minus the dumpster worthy "Made in China" rubber dome keyboards). Oh well.
