I've used CafePress for some books. They're not cost exxective for floppies, but I like the overall quality for Trades. But nobody beets Lulu for perfect bound, and while it's a bit more expensive, you can even do color trades
that looke REALLY nice.
And if you want a decent, but still small print run rather than Print on Demand, Brenner has adjusted their print run ammounts and prices to compete with the smaller POD services and they, of course, have EXCELLENT quality.
