My wonderful hubby said I can buy a new machine for quilting

I am very new to quilting (I made my first at Christmas last year.) My question is, should I get a newer or vintage one? I honestly have no clue what to look for in the way of quality, etc. any suggestions? I love the way the old ones look, but are they really good about going through thick layers? I have a Janome Class Mate (model sold to schools) that I got used after only 2 years at a school, so it's still pretty new, but has a hard time going through denim

I appreciate your comments!!
