To make it worth it, get a Mini... a B&W G3 needs some TLC to run Tiger decently. Might as well get a Mini or an older eMac...
Sound advice, but there is a big cost difference between a properly equipped mini (with enough ram) and a B & W G3, and he said he wants to spend $100. A mini with enough ram will cost well over $600, plus either taxes or shipping or both. He can get a B & W G3 with shipping for $100 or under if he is careful and patient. HUGE difference if you are basically broke. As for being afraid of ebay....if you are careful and check out the sellers carefully, no problem. As long as a computer works, is sold by an honest seller who packs well and fully discloses the condition and what items are included, and as long as the computer is not smoke damaged or tainted, then you have no worries buying off ebay. Now if you eschew ebay because you hoped someone here would just send you a relatively recent Mac for free, then I think you will not be happy with your outcome. While it is possible for someone to give you a computer (I have a 7300 I am prepared to give away right now), getting one with real value is another thing altogether. ("Getting one with real value is another thing" says the group in unison)
Yes, you could run Panther on a 7300, and pretty well (with a G4/450 card, that is, and at least 512mb ram, using XPostFacto), but I don't think you would be happy with the experience. The video performance with .wmv files for example is hideous. Most everything else is useable.
So, do you want to test out the Mac experience CHEAP, or do you want to do it right? If do it right, then save and get something a bit newer and more expensive, like a mini (as Mechcozmo suggests), or a used G4 or G5 PowerMac (which would be my suggestion--why? because there is more upgrade possibilities, and thus more life potential in a PowerMac, and because you get the most computing power per dollar with a tower). If cheap is still king, consider the B & W G3, or any other old Mac newer than that.
