RE: optional purchase
The trouble a lot of people find with "outdated" models, is when they try to sell them they find the prices offered for them are insulting to say the least. The trouble with many is when they purchased some of their rifles, these were top of the line and they paid top of the line prices. Now that they want to sell them, while not expecting the same as they paid, they don't expect to take a 50% or more loss in the value.
My advise is keep the rifle. There is always room for one more in the gun cabinet. Someday in the future you might want to give that as a gift, or load to a friend. Simply continue to save your money, check all the different sites that offer the kind of rifles you are interested in, read all there is on the different models, and when you have the money to purchase... enjoy your new rifle.
