God, STAY AWAY FROM CHERRY MY, or more commonly known as the mechanical switches designed to feel like rubber dome. Yuck I feel filthy just thinking about it.
BTC 5100c is some with slider. It arguably the best that rubber dome can get, but it is at the end of the day a rubber dome.
If you want vintage AND compact then your best option is the SIIG minitouch with monterey switches, aka SMK 2nd gen clickly switches. Some minitouch comes with alps skcm white alps though, so that is also great but the first option is by far the best. Be careful with SIIG minitouch
plus, that is a rebranded BTC 5100c, or the other way around I dont remember.
The more common one you may encounter is the Cherry MX 11800, which can have brown or black switches. This is I think a good option. They can come under the brand of compaq, so be aware. An example:

P/S: beware that alps is not for eveyone as it is heavy
