Try out as many different models as you can to see which setup works best for you...which is easiest to manuever, weight of the machine, etc. Make sure you will have enough room in your house to fit the table size you want. Check into service and warranty...if you have a problem, how easy will it be to get help either on the phone or from a dealer?
With all that info, we decided on Nolting machines, first with a Fun Quilter and then a 24 Pro Series. Would highly recommend the machines AND the service the Nolting has. Top notch in our book.
