IMO even the expensive Shapeways materials give only just acceptable results. There will still be some printing marks on curved surfaces that will need sanding smooth. Edge details are too rounded - they look like they came from a 10th generation recast!
And since I'm in a critical mood I'm going to say that none of his ships are as great as what they cost to print. They are missing a whole level of detail that would be required to make them look right among the rest of the Imperial fleet. The general design of the transports aren't too bad, but they're mostly copied from the existing transport designs, so it's kind of hard to go wrong. Like I said they just need more detailing...
