My brother had a Pentax Lightseeker. I found it to be very comparable or probably even a little better than Leupold. It's not as good as say a Swarovski or a Zeiss Diavari, but a good scope for the money.
Another scope you might want to look at is the Zeiss Conquest line. They are really good scopes at a similar price to the Pentax scopes.
Camera Land, Inc. usually has great deals on both of these brands (Zeiss and Pentax). Check it out. I had a really good experience there. Their demos are really a bargain.
Hopefully this didn't complicate things more for you !
I put a Zeiss conquest on my model 70, and I love that scope. I was looking at the pentax because it is compact and light, I'm going to put it on a tikka t3 lite. Now i'm also looking at a Leupold vx3 2.5-8x36. I just need to make up my mind and buy a scope.
One of the most important pieces of equipment that you will take hunting is a good quality pair of optics and they take some care to give you the performance that you want. So here are a few tips.
Use some alcohol and cheese cloth to clean the lenses. I will usually pick up an extra cleaning kit from my optician when I have my eyes examined.
Don't touch the lens with your fingers. If there is a stick or a bug on them blow it off.
Use the lens covers. They are there...
