It's a tough market for that bike. You have the frame, which is great, and you've removed the horrible lavendar decals, which were the only thing Centurion about it.
With it's mix of Universal AER brake set (fine set, too), Ofmega Mistral crankset, bb, and headset, and Campy NR other stuff, it tends to turn off some folks. However, they are all great components, work together well, and I like the bike.
Mine was probably a little cleaner than yours, but your non-Centurion decals are probably better. I paid $356, sold it for quite a bit more, and now it's Ferrari Enzo red with the fork all chrome. I'll have $1100 in it with a full 1989 Chorus group. I'm going to peg yours at $700-$800 as the market for that Cinelli-branded frame gets steadily better. More if you sell it on eBay, but it needs to be spic and span.
