Just so you know, cheap is probably the worst thing you can do. You probably need to get some work done and need to tool up in a hurry and I understand your budget is probably limited - so is mine. But cheap tools are a poor investment.
Get the basics (hammer, pliers, hand saw, measuring tape) in a known brand that has lots of recognition, like Stanley. Stanley has products in each of those categories and even their lowest-tier offerings are sturdy and reliable. They won't be as cheap as the cheapest things from Harbor Freight, but they won't break your bank and you can get started on getting stuff done immediately.
For more esoteric stuff try Harbor Freight. If you know what you're about you can get decent equipment at a low price, especially if you overbuy for what you're doing. For instance, a 13-pc set of 1/2" drive impact sockets at HF is $25; a regular set of 1/2" sockets at Home Depot is $31 - and only 11 pieces. HF's brand of impact sockets aren't as good as even Home Depot's brand of impact sockets, but they're way stronger than HD's regular sockets. You won't be able to break them in regular use. So try HF and buy the heavier-duty stuff there for your regular-duty use.
Except for Harbor Freight cordless tools. Just don't. Go to Home Depot, get Makita cordless tools. You won't be sorry.
