It all depends on the brand name of the scope you want.
Last week I purchased a DOCTER 3-9x40 for $ 359.00 at
Natchez, and last month a Zeiss 3-9x50 (yes 50 mm) for
$ 439.00
Natchez is also very good with the Burris brand...but those sales sometimes last for a month or so. It varies w/ brand name and supplier.
Just keep watching the websites-sales ads and you may save a hundred $ or more on any particular model.
Oh, there is another by the name of skyoptics.com that also
have some good deals.
Good luck to you all...!!
