Hatsan are probably about the best of the cheaper new stuff but they're still not a patch on a good quality used rifle.
If you buy a cheap gun new, you'll probably want to 'up grade' at some point in the fairly near future and you'll loose cash when you part-ex, sell, whatever.
A used gun's already suffered depreciation so if you buy well and look after what you've bought, it'll always be worth pretty much what you've paid for it.

But the Hatsan is well made and is a gun you can keep! I have one and speak from experience. I only went for a Stingray as I wanted a .177
