When buying tools you can save a lot of money buying non brand names, when I worked as a pro mechanic I always bought pro equipment but if your buying tools just for modding at home which get relatively little use you don't need expensive top end gear and the smaller lite versions of some tools like scroll saws, pillar drills and even welders will be more than sufficient for most people and don't take up too much space, a pillar drill/drill press is nice but I have actually used an electric hand drill in a cheap drill stand for years and it makes drilling holes in a straight line through thick material much easier than holding a part in a vice and trying to drill a straight line through it!
