Buying ryobi 524 hx

I am in the market for a 20" 4 colour press. Always had Heidelberg machines in my shop, except for a KBA SRO4H, which turned out to be a big mistake in my opinion..............Any ways, I was looking at 1990's Heidelberg GTOV with cpc, and someone offered me a good deal on a 1998 Ryobi 524 HX, with PCS control. Can Any one give me some feedback about running their Ryobi 524 HX, which press of the two do you prefer? and why? thanks.
