The Necchi you are looking at is one of the favorite machines for FMQ. It is heavy, but very well made. I don't think you will be sorry, and that looks like a good one. Many people swear by it's fmq abilities.
I also urge you to look into a Singer 301. I have quite a few machines, including one Necchi Super Nova, and the 301 is my all-time favorite machine for fmq (and piecing, and straight-line quilting). Compared to the Necchi, the 301 is bulletproof. There is nothing wrong with the Necchi, it's just that the Singer 301 is as close to perfect as you will ever find for fmq. It's basically trouble free, and easy to operate. And yes, the Singer 15s and Model 15 clones are good, but I still prefer the 301.
You can maintain a 301 yourself, but probably not a Necchi unless you have additional training or experience. I recently took a Necchi apart for servicing (I have the training) - it had concrete dust in it - and it was not the easy job that the 301 is.
