another good source is Ford Electronics in Fullerton CA - they used to have
a reasonable selection of large surplus resistors

They are about 5 minutes from my shop in Fullerton. Ive driven by there
a number of times in the past month. Ill have to stop in and see what
they have.

The large open end ones with ribbon wire - are called 'corn cob' power
resistors.

I have two smooth sided resistors - each 8 ohm (nice speaker loads)
but must be 1000 watt. I'd have to look. I also have a 1/2 ohm IIRC
corn cob. Nice to measure current flow in a circuit - voltage drop.

$33 isn't bad for that - I'm surprised myself.

If you get one, look for mounting hardware. It helps. Or you make
some.

I like the ones in aluminum housings, like these:

They are less fragile than the ceramic ones, and tend to be a bit smaller
for a given rating. Several vendors make them, and they are available
surplus from time to time. Be careful with the power ratings, however.
They assume a certain level of air flow & heat sinking for continuous
duty. For the 200W braking resistor, you could probably get away with a
200 W rating without heroics because the load is transient.

"First Law of Leftist Debate
The more you present a leftist with factual evidence
that is counter to his preconceived world view and the
more difficult it becomes for him to refute it without
losing face the chance of him calling you a racist, bigot,
homophobe approaches infinity.

This is despite the thread you are in having not mentioned
