Take some scraps of the fabrics that you plan to use (wovens are easier to start with than knits but a good stretch stitch on your machine will help a lot) to a sewing machine dealer. Tell them that you want to look at their used machines.
A good dealer may offer classes (for a fee) and can understand that if the used machine you buy today gets you interested in sewing, there is a very good chance that you will come back to them to buy a newer machine as soon as you can afford it.
The used machines should be cleaned & oiled before being sold - so sit down and try out the machines to see which ones sew well on your fabrics. After sewing from one corner to the opposite corner on a five inch square (on the bias) try to pull the two corners to see how long it takes the stitches to break. Turn back one layer to see how the stitches look (that is what will be showing from the outside of your garment).
Readers' Digest has some very good BASIC books - one came out in the 1970s, one in the early 1990s, and a third more recently. Used bookstores (or Amazon) may have a copy at a smaller price - any will work even if the suggested projects are a bit dated.
Three things?
Buy good fabric, good needles, and good thread - you can't make a good project with bad materials or bad tools (same thing with cooking - rancid butter and old eggs will not make nearly as tasty a cake). Ask a man if HE'D use cheap tools and warped wood to try learning how to do woodworking (if he says yes, don't ask him to build you a bookcase).
Even experience sewers end up ripping out stitches some of the time. I've been sewing for over thirty-five years - I've worn out a few seam rippers in my time!
Third, sometimes it's just like the line from an old country & western song, sometimes you have to walk away from the sewing machine table for a while. It is a mistake to cut fabric when tired (and cutting the project too small is the hardest thing to recover from) or sew along the correct seam line when you are tired (guess when I do most of my ripping out?).
(Singing "know when to hold 'em, know when to fold 'em, know when to walk away, know when to run".)
Quiltropolis and Yahoo have groups that might have the same interests and even a member in your area to talk to. The local fabric store may also have classes.
Simple project that might come in handy right now - pillow cases, fancy aprons, and drawstring bags for gifts. Same project with a zipper and you have a bag to keep your makeup in or put in your suitcase for toothpaste, toothbrush, and shampoo.
