Greetings from Sacramento CA.
When I got bit by the quilting bug, I took a sampler class to learn about the techniques at a beginner level. Each session built on the previous and it really helped. Just moving from scissors to the rotary cutter was a challenge in the beginning.
As for the machine: I actually have 3 different machines now and I use them all for different reasons. One is a low end $$ for taking to classes. My work horse is a Pfaff with a built-in walking foot. Then I reecently got a Pfaff GrandQuilter for quilting. I took a loooong time researching the machines because they are expensive and I wanted to get a good match for my need.
I was intrigued by an embroidery/sewing machine but realized that it wouldn't be good for me. What would I do (sewing-wise) when the machine was doing "its thing." Hope you find a good match for you and that you enjoy the experience.
