There have been DIY 60% boards, the Plain60 is still available if you want a standard layout, if you want a weird one the

Matias whose switches/boards are Alps compatible. They had (have?) issues with chattering switches but I haven't heard any in a while... The Ergo Pro is my favourite off-the-shelf board, no learning curve whatsoever despite the split. If you don't mind desoldering the odd failed switch definitely an option.
