Xxcristiixx, I don't mean to sound disparaging, but your first post here was to ask for someone to give you a uke for free. You haven't introduced yourself or given us any valid reason why you can't afford to buy an inexpensive uke.
A lot of us are having trouble making ends meet these days. Unless and until you have given up every possible luxury, then you should be able to cut back somewhere and save up $50 or so to buy a uke in a month or two.
I don't eat at restaurants, or buy coffee from Starbucks. I don't go to the movies. I wear multiple layers of clothing and fingerless gloves to avoid running the heat. I study the weekly grocery ads and try to buy what I need only when it's on sale. I walk to the store when I can to save gas and wear&tear on my car. I even cut my own hair.
I have managed to afford a few ukes. To me it's all about priorities.
I do not know your circumstances, but perhaps there are some corners you could cut to save for one. Or maybe you have something you no longer need that you could sell to fund one. Have a yard sale.
