Really depends on a number of things mate, your budget, Illuminated reticle interest you? For hunting, personally I'd say go variable zoom, gives you better field of view options and more versatility. Do you want a paralax adjustable scope? Improves accuracy (when used correctly) Sidewheel focus (paralax) is less hassle than the AO type but generally costs more..
Leapers Accushots are actually re-branded A.G.S. SWATS and cost around half the price.. Good value for the money. (hands off the one Maverick is selling please!)
Going higher.. Bushnell Elite 3200 http://www.airgunbbs.com/forums/show...light=bushnell have quality optics and the 4200 range better again.
Give us a few pointers?
