Wooting.io is really the best at hall effect keyboards. They were the first and have been leading the pack since their inception. I own an 60HE and an 80HE. Both are excellent. Though I tend to migrate back to the 60HE personally. They have fullsized boards and a full set of open source software for macros. Their keyboard config software is web based it, though they have a stand alone version if you'd rather.
If check out bad seed tech and optimumtechs videos (YouTube) on wootings boards for more info.
