First off if you are going to sew you can't embroider. The machine will do one or the other but not both at the same time.
Your best bet might be going to a dealer as you have after service support and lessons. The price range may start around $500 and go up depending on what you want to do. Getting a machine with some weight to it means the machine will stay put when sewing and not slide on the table. Take some of your work with you to "test drive" the machines in qusetion. Quilting take several sandwiches. Jeans take several layers. Check out how the machine(s) handle the items and the sound of the motor. Does the motor sound the same or is it laboring with the work?
Embroidery machines. So far I have found the Brother to be the easiest to work with and download designs from the web. Hubby got it for Father's Day so technically it IS his machine. The stitching is tight and looks great. I have a Bernina and a Viking that I have to learn how to use the embroidery modules and each have things I like that the other doesn't have.
Industrials are more for sustained use over a long period of time like four or five hours straight. Your home machine will do this but it will complain.
As the book states they are meant to do a certain number of things only with great results. Whereas with home machines they do many things quite well.
The lighter weight plastic machines are fine if you can't lift much weight and check into where they are made. Many machines even high end are being made in China.
Write a list of the things you want your new machine to do and see if the dealer can come up with a machine that will fit your needs and allow you some room to "grow" into your machine.
Good luck to you and enjoy your sewing.

PS I had a Singer from Italy and did quite a few military uniforms on it and the foot pedal would be warm after sewing for three hours straight in the morning before work. I also wore out two other machines and broke the shaft of one -- these machines were all home machines not industrials. I still have the original machine I started my business with which is one of the last Singers and it is over 24 years old.
