I have the Hunter in .45 Colt and have on it a 2X Leupold. If you want a Leupold, I would suggest looking online and getting discontinued M8. Got mine on Ebay for around $120 shipped, nib. Nice clear optics and I can't complain about the price.
I don't know if I would recommend that variable that Redhawk mentioned... Oh no, I really love Bushnell scopes, a lot of bang for the buck, but if I remember correctly that scope was too long for the Hunter. Too long meaning that you'd have to take off the front fixed sight to get it on. I for one, always like to have the fixed sights ready to go if I break the scope in the field.
