can anyone recommend a brand or model that you have and works good ?
Last month I bought (or should I say, my daughter "bought" it for my birthday) a Leupold SX-1 Ventana 15-45x60mm with a case and tripod from Optics Planet for $320 shipped.
It ain't exactly the Leupold Kenai that it replaced... but for the money, it's clear and bright with only a trace of distortion on high mag at the very edges.
I think they have a few left... and some 20-60X80 Ventanas for a hundred more.
Almost forgot... as usual, the case and bipod are low quality.
