What are your budget constraints? Both Sigma and Tamron make decent "budget" 150-600mm lenses, but even those are in the $1,000 range and are not fast lenses.

The 75 to 300 is not that good of a lens.
If $1000 is too much for you, you can get a 1.4 teleconvertor which will make your 300 mm a 420mm equiv, which will be equivalent to a FF 672 mm.
I have had pretty good luck with my Tamron TC, though I don't use it much since I got my 150 -600 mm lens. 8^).

"I am a hobbyist on a small budget, ..."
Aren't we all?
Here is the cheapest option and it does a 'reasonable' job but keep in mind it is totally manual. Completely manual. The Opteka 500mm f/8 High Definition Preset Telephoto Lens for Canon. It is 800mm on your Rebel. If that ain't enough, I don't know what is. These sell in the $100 range. New!
Your next and better option is buying used. The big tele super zooms are goof buys on the used market. Somewhere in the $500 to $600 range.
Last choice, save longer.

They are OK:
They certainly get you the most bang for the buck. I had pretty good luck with the Tamron. I would not trust Vivitar or Bower, though.
If you find the 75-300 acceptable, they should be fine.

"What is everyones thoughts on teleconvertors?"
I don't like tele converters. But I admit there are a few, very few, lenses that handle them really well. The Canon 1.4x on a ef 70-200mm f2.8L for instance. Works well.
I have maybe six or sever converters and I have had another six or seven in the past. Don't like'em. I have the Tamron and the Sigma and if you must buy one that is not a Canon brand get one of them. Then only the 1.4x versions. Never the 2x.
The best third world converter is probably the Kenko 1.4x.
Don't waste money on the off brands, Bower or Vivitar.
