HW95 would be a great choice, but I would think about going used. Oftentimes, you can get a tuned used one for the price of a new one, and not even have to break it in. Since you can't be so picky used, here are some other options:
Beeman R9 - Almost the same gun. No sights, slightly shorter barrel, slightly different stock. Usually more expensive.
Tuned Xisico from Flying Dragon - Not the same build quality, but as they're tuned, you won't have issues.
I wouldn't discount PCP, either, like a used Marauder in .177 or .22.
Used Beeman R1
Walther LGV Ultra - newer technology, better tuned from the factory, and quieter than the HW95/R9. A little more expensive I think, and the styling is more modern.
