I wouldn't put the large extension table under the 'needs' column as you can always have one made later. We have a great plastics company here that will make yours to fit. Also, at one of our mountain retreat sites there is someone who will make whatever you want, he just needs to know which machine it is for. I just ordered his 'easy release' feet to go with my ex. table as the screwing of the existing legs was getting to hard for me to do.
Several different sites also sell them, but that usually costs more.
Get the machine with the machine features you want first. Just make sure you can BOND with that machine and have local support.
