Scoping an 11/87 Question

[copter wrench]

 Bought a saddle mount from Bass Pro(picatinny rail). On the fence about scopes. What is the difference between Simmons Master Series pro diamond 1.5-5x32 and pro hunter 1.5-5x32. Natchez shooting has the Master series for $49.99 and pro hunter for $69.99. They also have the Tasco world class proshot 1.5-4.5x32 for $41.99. Read lots of great reviews on the Simmons on this sight.

I would appreciate some guidance, I'm ready to order tonight. Got into Turkey hunting last year, had birds coming in a couple of times, but I moved and it was over. I'm hooked.
