As mentioned above the old vintage Bushnell Spacemaster is a great value and it will likely have a 20 to 45x eye piece.
An alternative might be an old vintage Bushnell Sentry which is the same as the Spacemaster except a smaller objective and a fixed 20x eye piece.
The Sentry also does not focus quite as close as the Spacemaster... if you're an airgun guy, then get the Spacemaster.
I have both actually and find them to be the very best value and anyone considering a new scope should buy and try one of these oldies first. It might just be good enough.
I also have a Kowa 554 and obviously the old Bushnells wont compare to that, but I recently sold off a Vortex Viper spotting scope that I would be hard pressed to say was any better than either of the old Bushnells. (Which is why I sold it)
This might sound bold, but I dont know if I would buy any new $1,000 spotting scope over a vintage Spacemaster or Sentry.
If I wanted to spend more, I would look for a Kowa with Prominar glass from the 90s or so. I've seen them on ebay for around $600, and they will be close optically to a new $2000 scope today.
Here's a couple nice ones on ebay, but if you look around you can find them cheaper.
Pay attention to the eye piece!!

In bright sunlight you can see mirage easily with the old Bushnell scopes, but not very well in overcast conditions. That's were the big money pays off.
