Firstly, I want to welcome you to the wonderfully addicting world of sewing/quilting! Everyone here has offered you sound advice and I hope do hope you heed their words.
Please do not put yourself at the mercy of a big, fancy, expensive machine that will undoubtedly overwhelm you and possibly cause you to just drop the whole idea because it's too complicated.
Start with the basics. I bought my very first machine, a Sears Kenmore, from a lovely lady at her yard sale. That was back in 1978. I gave $25 for it and it's still going strong! Since then, I've added a couple of Featherweights and a couple of more advanced machines to my collection.
Start with a reasonably priced basic machine that you can learn the basics on. Try craigslist, yard sales, or even ask your friends (and their parents) if anyone has a good used machine lying around they no longer want/need. Good luck!
