Night Vision ?

Hi all
I have a couple of Tawny owls feeding on the mice and voles attracted to the spilt seed around my feeding station in the garden. I have toyed with the idea for years of buying a night vision scope or bins and feel it would now be worthwhile for bat/badger/owl watching here in Edern. There seem to be dozens of models and makes on offer, so my question is does anyone use these or have a recommendation ? Obviously I don't want to pay silly money but I don't want poor quality either so I am prepared to pay a decent amount.
