The 12" is too big I think; just takes up too much real estate. I'm not too concerned over the bed warping as I planned on getting the AL bed upgrade. The weight difference between the two isn't that much. I asked Colin and although he did have numbers for the 10" bed he gave me weights for the 12" and they were only 5 ounces different. He guessed that the 10" was probably about a 4 ounce difference between the wood and AL. I was more or less concerned with the frame strength/rigidness by scaling the 8" printer to 10". I figure I can print smaller things on a bigger bed, but can't print bigger things on a small bed. I was just asking because if the 10" was plagued with issues or print quality inst the same or something else like that then I would just stick with the 8". I was just hoping for first hand experience.
