+1, but $100 possible.
I strongly recommend against this if you are new to straight razors. Honing a straight razor properly is a skill set that you would have to learn on top of learning to shave with a straight. You would be trying to figure out what the problem was, shaving technique or a bad blade edge.
To start you need 1) a shave ready razor; 2) strop; 3) shave soap/cream; and, 4), a brush.
Check the classifieds for shave ready razor. Something like a 5/8 or 6/8 round point that is shave ready (will state so in the add). I have purchased a few of these. They are really nice razors for a fantastic price. Kenrup, a member here, sell great starter sets. Also check some of the other vendors. SRD comes to mind. No matter where you get the razor ensure it is shave ready.
Check the classifieds again for a strop. Check our vendors. Many sell starter strops for great prices. Also, people have been known to use newspaper, denim, or other materials as strops.
Shave soaps or creams (personal choice) can be had in a lot of places. Many people here use Williams which is quite inexpensive. Check the classifieds, sometmies you can get great bargains there. As for a bowl, a large coffee mug works great. Also, go to a dollar store and look there. A bowl can be had there. You don't need to spend $50 or more when a cheap bowl or mug performs just as well.
Brushes can be had pretty cheaply to. Google on "shaving brush". :gl:
