Have a Bushnell Elite 4-16x40 on a Lux, seen lots of dead gophers through that one. Bushy Trophy XLT 4-12 AO, Vortex Diamondback 4-12 AO fit in the budget. I don't like exposed turrets in the field, ok for a target gun. Have the same issues with the Timberline as mentioned, I blame it on bi-focals. Have a Vortex Xfire II 6-24x50 on order to replace the Timberline. Lots of opinions and choices, good luck in sorting them out.
