Catalogs are good places to start. Craftsman, Harbor Freight ( for things you
only use once), McFeely's for fasteners, etc. Go online to Amazon.com for
collections of trade specific items, like all kinds of stuff for drywall work.
For electrical work, buy the new Klein Tools 14, 28, or 19 and 41 piece
Journeyman Tool sets. They aren't all that pricey, you will get a ton of use
out of them and be the envy of all the electrical DIYers. Try to get a decent
sized all year around workshop going as soon as you can. Then buy a good table
saw, preferably something like a used Delta Unisaw. Let the project dictate the
tools, rent first if not sure. HTH
