I bought an EGW 20 MOA base for my MKII, same receiver, and it was about $35.
As far as buying and swapping barrels? You may be better off just selling the gun you have and buy the one you want. Probably not what you want to hear, but certainly cheaper than a $600 barrel! You could get a complete gun for far less than that. Savage rimfire guns are relatively inexpensive.
