Just do it and don't look back. The night I ordered the Glove80, I almost bought an Alice in Amazon but I got the one I really want. Half measures might have given me buyers remorse.
While I have been eyeing these "cup" style keyboards for years, I feel very hesitant dropping $400 on a keyboard when my Alice is "fine".
Maybe you are right that Alice is a half measure and going full hog is the way, but I could also be spending $400 on a keyboard and another $100 on shipping on import tax just to end up with a keyboard I don't use.
With hot-swap you can just buy a set and if you don't love it you don't need to buy a whole another keyboard.
But I do get that some people know exactly what they want, but I often need couple tries before I get what I like.
(For MX style, I do prefer clicky or tactile).
