Inherited a MEC -think it is a sizemaster

[King Cobb]

I just inherited this press along with a mess, and I do mean mess, of other reloading odds and ends. I have a Mec 650 already that I have toyed with the idea of sending back to mec to setup for 2.5 inch shells but now I have this other press as well. The 650 is a more or less progressive press and the sizemaster is obviously not.

I am possibly contemplating selling both and getting mec to make me a a 2.5 inch press, but if I do that which press should I get. I don't shoot a lot of rounds a year, would love to shoot more of course.
