I like a decent pump a lot better. My favourite pumps are the Zefal HP or Zefal HPX.
I agree. And I had some luck with my HPX the other day. I hadn't used it for a long time, so
grabbed it instead of my floor pump to inflate my tires.
Well! I couldn't get it to switch from "X" mode (for clipping into my bike frame) to "HP" mode
(for actually inflating the tire). It took several shots of lubricant into the fancy 2-way handle,
plus a lot of working things back and forth. And the steel pump shaft was a bit rusty too.
I cleaned and lubricated that plus the leather washer.
I was glad I learned this at home instead of on the road. Moral of the story: Maintain your pump.

Silca is coming back to life and perhaps they will use their own pump technology to build full sized frame pumps if enough people write them about it.
???
Silca USA has made them, very well, for about six years.

How easy is it to get the Silca up to say 90 psi and can that even happen? I have no information on them other than they are a frame pump. My assumption is they probably are much easier than any mini pump.

Define 'easy' !!
They're not light - heavy aluminum construction compared to
a classic Immpero. Heavier than an HPX too. By a lot.
But tough. Besides dog flailing (much discussed,
infrequently practiced) you could really hurt a man with one
of these. Made much like a police baton with a rubber seal
inside the end.
Diameter is smaller (20mm) than a classic Impero (21mm) but
larger than an HPX (17mm) and most minis (17mm & smaller).
With your typical young rider's physique it's great. Riders
who are less strong will fight to inflate to road pressures.
Long is a feature but as we all know from HPX, long and
skinny is better for most purposes.
My daughter OTOH defines 'easy' as asking me to drive 180
miles each way to change her tires. I was there last evening.
