Love this machine – I had a budget of $500 and this machine was in that price range. It is very easy to use and the manual is clear and easy to understand. I have only had tension issues when using cheap thread/wrong needle. Any issues were down to human error or inferior products, not the machine itself. I don't have any complaints about the machine and it does everything I need. Came with a 5 year warranty on all computer parts which eased my worry about a computerized machine. Has sewn through quite a few thick layers, although I don't quilt, so maybe take a sample in store to test, but I think it will do great. Computerized functions like auto-locking stitch and needle up/down, speed control options, easy to use. Slight humming noise on start up which then fades, doesn't like the cheap thread I used.
