I'm a furniture student and i personally bought, mostly from ebay. Old bevel edged chisels, various sizes (cheaper than new ie. AI, or Lie nielson, etc.) SIzes... I would get one big one, (2" around there) and then 3 smaller ones. Old steel is better than new, (to a certain extent) from what i've read.
I bought a Japanese pull saw and it's very fast to cut, but requires a little practice.
Jack plane, i bought a Record no. 5 1/2. old stylee.
Even if you buy new chisels and a saw, i think the most money you can save is a plane. They are readily available second hand. All you really need is a Sharp blade, and a flat sole. There are many flattening sole plane posts on the forum. Plus even more sharpening posts.
BTW. U will also need to buy sharpening stones etc. oil, water, diamond, ceramic, wand, jacob....its up to you.
I'm just a beginner in the wood world, and hope i have helped you in some way, Cheers.
