- 20oz. Estwing hammer (the one with the blue handle); will last you a lifetime...$20
- a cordless drill: Milwaukee makes top products but you may not want to spend that much....$30-80
- duct tape...$4-5
- assorted screws, nails...under $10
- assortment of Craftsmen screwdrivers to supplement your drill (optional I guess)....$20
- Vise grips (better) or regular pliers....$5-12 or so, depending on size
...some things I could think of off the top of my head.
Just remember that the choices you make now on your tools, especially power tools, can and will effect what happens in the future...spend the $$$ on a high quality tool now and you won't have to replace it probably
ever in the future. Plus with spending more $$$, you get the better features, power, etc.

*edit...brain fart typo...meant "20oz" instead of "20in"
