I have had a 6600 for eight years and love it. I also now have an 8900, delighted with it. Either of these machines would be ideal for your needs - the 6600 has 9" throat and the 8900 has 11". The 6600 is a 7mm and the 8900 is 9mm. For FMQ that extra two inches does make a big difference. I use both machines all the time.
