The issue for us is that we have been using scuba tanks to fill our PCP rifles and driving forty miles one way to get them filled at the nearest dive shop. The tanks, though, are now out of date and will need to be pressure tested, again, to be safe. That's a whole different headache, since that will require a drive of hundreds of miles. Just not practical.
Back when we got into PCP air guns, there weren't any affordable options for compressors, anyway. Things have sure changed these last few years.
So why bother with PCP air rifles in the first place, you might ask? This is why and these are only average 50 yard groups for our Daystate PCP. Believe it or not, I've shot even better groups with it.

Oh, we could fill this great PCP rifle with a hand pump, but that would require about 150 pumps with our PCP hand pump and take well over an hour of really hard work, not counting rests in between to let the pump cool. At our age, not an option. And we will never part with this rifle, a vintage Daystate CR97.

After researching this choice of compressor for literally months and months, we narrowed it down to two, both of which have received great reviews from owners.
First is the surprisingly compact (and relatively affordable as compressors go) AV Nomad II

The second is the more expensive AV EC-3000, but, unlike almost all the other compressors we looked at, it is made in England, not China. It's also air cooled instead of water cooled, which is a better fit for our cold northern climate. Very simple to operate and great construction quality, too.

We decided to pay more and go for better quality and ease of use with the EC-3000. Will let you know how it works when it arrives.
PS
We also added one more Daystate PCP rifle to go with it, but that's another story. Here's a teaser, though. Shows what state of the art PCP rifles can do.
