Best quality keyboard in your opinion?

[bocahgundul]

A custom of course! The realforce and model M/F are really solid too. There's quite a few keyboards that I don't have any complaints about quality wise.

I have to say that custom is always best quality but the OP didn't stated what board so I could say that he mean a board that can be easily bought not like custom

For stock boards, Ducky, Filco, Leopold, Realforce, HHKB, all are generally considered top-tier in quality. However, I think given the choice, customs like Winkeyless, GON, etc, are pretty much THE top of the line in terms of just how good a keyboard can feel.

If your not saying Leopold fc660c  you must be high as ****.

I second this! The Leopold is an incredible stock Topre board :'D
