I just bought the 8900 beginning of January. It was a demo and I paid $2499 plus tax, including the acrylic extension table. New he wanted $3299. I don't think your price is too terrible. I have had the 6600 for 4 years and it's a great machine but if I was quilting queens and kings, I would definitely buy the 8900. The extra harp space is worth it. Plus I find it much easier to FMQ on the 8900. The 6600 was a nightmare to FMQ on. I LOVE the 8900. Originally I was going to sell my 6600 after getting the new one but it's pretty usual for piecing when I'm in the middle of quilting! Let us know what you decide.
