Bo,
I own several brands, Bushnell Elite 4200, Banner 4x, Sportview 4x, Burris 3-9 FFII, Millet silver 6-18, Mueller 8-25 tactical, and Hunter Wicked 3-9 and 3-12.
The elite 4200 is great glass, the burris is clear and sharp, the Mueller is exceptional for what it is and the price, but the scopes that I am more impressed with lately are the Hunter brand. They are fully multicoated with lifetime warranty. The glass is as close to the 4200 that I have. I found out they are assembled by Burris using Schott glass (German) and Hunter is making limited quantities. Natchez shooters has the 3-9x40 for $99. Some are using them on air rifles and 50 cals.
Had the 3-9 on a bull barrel rifle, sling came undone, it dropped to the floor from about 3 feet dead on top of the objective lens, visibly bent the scope. Locked up the elevation mechanism, took a crowbar and rag bent it back! Shoots and adjusts great!
Don't have the Pentax, but it sounds like a good scope for the money. I my opinion the Hunter 3-9 is exceptional for the price.
