Should I purchase a hand driller?
A hand powered drill will be satisfactory for drilling small holes in plastic pipe or even in wood. It will not be so good for drilling holes in concrete, glass bottles or metal items. The problem with the latter is that you will spend so much time drilling the holes that you are likely to get discouraged and never arrive at the point that you can determine if you have a satisfactory ability with DIY type projects. You really should look at some AC powered electric drill models. You can find some entry level models with very reasonable prices.
