Both are excellent. I would lean Rodagon based on my purely subjective experience but I doubt I could tell them apart is tested.
The prices are high (compared to the used market liek Ebay) but you are buying from a reputable dealer and for those prices I assume that the lenses are in pristine condition. To give you a sense of scale, I bought a Beseler 45MXT enlarger, 45S Dichroic light source, and a 3 lens turret loaded with a 50, 80, and 135 Nikkor lenses (pristine) for $250 but I was patient and lucked out.
