I went with the Redding. I like the solid support at the back of the turret, the height of the frame opening, the tube that can be used to collect or direct spent primers into a garbage can, and the 7 die stations. I bought mine only a few months ago for $174, but now I see prices have gone up. Midway had them on sale not too long ago for under $180.
The RCBS seems to offer more accesories, if that interests you, and I would expect it to be an excellent reloading press. Coin flipping time?
