My first sewing machine was a Brother CS6000i, and I have been using it for the last 5 years of cosplay work and minor repairs. I have taught myself how to sew with it and, well, it's just been great to me. Usage is fairly simple and even threads the needle for you if you just guide it. I've tried using my mother's old one and that required self threading (with the closed one eye 'n all) and was real fussy due to its age...
I still don't know how to really sew things, but all I need is a somewhat straight line to keep the pieces together! There are many stitch functions (like 100? including zig-zag), but I've only used a few, so this model might not be for you if you only require practical and simple stitching. I bought it partially with a Walmart giftcard--it was around $170+ back then...
I don't have any cons for my sewing machine. It has served me well over these years.
I hope you find one that you will like! Oh, I think Target is a good place to purchase from because they have a great 90-day return policy.
