Much simpler to just make sure the bike has a couple of water bottle
mounts when you buy it...

True, but the original poster bought a very inexpensive Huffy, likely at
Walmart. On these bikes they don't have the factory include such
expensive luxuries as bottle mounts.

Now he has to choose from one of many choices:

1. Buy a jig for $50 or so, buy a right-angle drill or close-quarters
drill (or a right angle adapter), buy some Rivnuts, buy some paint, and
install bottle mounts directly into the frame. Perhaps drill a drain
hole in the bottom bracket.

2. Build a jig or try to drill accurate holes free-hand without a jig,
buy some Rivnuts, buy some paint, and install bottle mounts directly
into the frame. Perhaps drill a drain hole in the bottom bracket.

3. Use a kluge like hose clamps or cable ties.

4. Buy an accessory that creates water bottle bosses with clamps or
straps that go around the frame tube.

5. Use a handlebar or seat bottle cage mount.

Most people would choose 4 or 5. It would be $5-12 well spent. Most
people would agree with the experts and understand that drilling holes
in their frame is a not a great idea. As Jobst Brandt stated: "I don't
know many riders who believe that drilling a hole in a frame tube is a
reasonable concept.", though on a sub-$100 bicycle it's probably no big
deal to destroy the frame if you screw up, and you could always use a
clamp that covers up the hole..
