I also have an X1c....that is the most used tool in my shop! It is a riot...I would highly suggest getting the best one you can afford, and also Bambu brand. Bambu, may not be the best one, but it certainly has the best support. It has its own "wiki" pages on how to fix them, complete with tons of youtubes. Parts are readily available, the company is reliable, and ships quickly. I knew nothing about them, and I am only moderately mechanically inclined. They tell you everything....and they do have occasional problems...so the wiki pages are very handy!!! And much like turning, there will be some additional "toys" required...watch the youtubes...."Meade Made" is one the best I have found...The class is not a bad idea, but certainly not necessary if you just use you tube..
Have fun, I have printed tons and tons of stuff....the next door girls have a lot of new Barbie beds and furniture, my wife has many new bowls, knick knacks and spoon rests, my friend with an HO railroad has some new buildings, and my shop has lots and lots of stuff, from storage containers, router table inserts, measuring devices, even a wrench from a carbon fiber material....It is great, mine rarely goes a day with out being run.....it is just plain fun.
BTW if you cast you can make honeycomb type things for the castings....
