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.
Let me start off by saying I am not a farmer.
I am a deer hunter and I do own a tractor and have all of the equipment - but that does not make you a farmer any more than standing in the garage makes you a car - well, you get the picture!
Having said that - and with most of my ineptitude fairly well hidden - I do think that buckwheat is one of the most under rated cover crops out there.
I say cover crop because I see mixed results as it relates to the deer eating the plants.
