Here are some numbers from the place where I benchmark prices for my wish list:
The only varmint model they show is this one:
http://www.budsgunshop.com/catalog/advanced_search_result.php?keywords=sps+varmint
and the same cartridge in the the regular, non-varmint configuration:
http://www.budsgunshop.com/catalog/product_info.php/products_id/97333
And regular in .243:
http://www.budsgunshop.com/catalog/product_info.php/products_id/97355
And .243 in Stainless:
http://www.budsgunshop.com/catalog/product_info.php/products_id/97263
Is the varmint model Stainless? They don't have a picture on that first one, so I can't tell. Also, there may have been a price increase, as searching that whole site for SPS shows some models @ $398, as if maybe it was last year's production.
Hope this helps,
