I always liked the Fuji approach. Good frames, good drivetrains. Go cheap on the seat. If the buyer is serious, he is going to swap it out for one that he likes. That seat's purpose is to make the bike ride-able for the test ride and so the bike looks like a bike.
I raced and rode the Selle Italia seats of the '70s for a couple of decades (under their and several other names. As I came into my 40s, my body changed andt hey stopped working. My riding fell way off. When I came back, I kmnew I had to find a seat that worked. I bought the previous year's Specialized Body Comp, the cheapest one, on sale for $39.95. Complete breakthrough. A year later, I bought the high end model of the same, took the cheapie off and put it on my commuter where I rode it another decade+ until it died. Never stopped being a very good ride.
