I've seen quite a few good photos where people used a 2x converter. Since they run from cheap crap to $$$, what's a good one to use on Canon EF ? Probably can't afford the best, and wouldn't use it all that often anyway-but I'd like to get a decent one. So far, the 75-300 is all I have in a zoom though I'm looking to affordably upgrade.

No converter will work (AF) with that lens. Best you get/have a late high MP body, the latest 70-300 IS II, maximize your image quality and CROP.

Probably using a 2.8 L zoom lens or f4 L prime. The lenses that work good with 2X extender are multi - thousand $$$$ !
You asked for the details. Already, the issue with your 75-300 has been identified. Specifically, your current zoom lens, and all of Canon's non L zoom lenses, are physically incompatible with Canon's extenders. You didn't mention your camera, but you will also likely encounter the problem that 1-stop loss of light will cause your camera to be unable to auto-focus a lens and extender that yields a maximum aperture of f/8 or smaller. Regardless of the brand of extender / teleconverter, if your camera cannot auto-focus at f/8, any 3rd-party converter that can physically be attached to your zoom will result in a manual-focus only configuration.
The two images below show the physical problem with Canon's non L-primes and all but a few L-series zooms. That is: the 1.4x and 2x extenders actually "extend" into the lens where connected. See the top portion of the 2x extender. The 'receiving' lens must include space for the top of the extender to "extend" into the target lens. All of the compatible L-series Canon lenses have this internal space between the rear lens element and the mounting ring of the lens allowing connection with a Canon extender.
Regarding an affordable upgrade, the EF 70-300mm f/4-5.6 IS II USM would be an excellent upgrade at the same focal length zoom (but cannot be extended). However, of you're looking for an affordable and longer focal length lens, here you should look at used versions of 100ish to 600ish zooms from Tamron or Sigma, for any options that fit your budget.

I have 2 of them for years, and I'm very fond of them, means I like them a lot. Mine are the 1.4 x III and the 2x III, both are Canon and for the EF line, I do not know if the lens you mentioned is compatible with one, but I have the suspicion, it is not!
