RE: $150 scope
If you can get a buckmaster at that price I would say go for it.
Others in that 150 range I would consider are the Bushnell Elite 3200's and the Simmons Aetec... I don't think the lower end Leupolds are worth it, just my opinion. For about 25 more bucks you can get a Burris 3x9 and spotting scope through Natchez, a great deal.
I hope that helps.
