I am looking for a good 60-degree, double-angle cutter. Carbide would be nice, but I do not want to break the bank. Have one that you like and would recommend?
3/4" or so would be fine. Any really big difference in tool life and quality of cut with the cheaper (not junk, just less expensive) double angle cutters and the $60+ ones from Niagara?

As with most things in life, when it comes to buying tooling the rules don't change--you get what you pay for. Yes there are some decent and cheap cutters out there but I've never found any that were consistent in quality...

The ones I got a few years back have given good service. I have several Grizzly tools and am satisfied with all of them. Presumably the current crop is of equal quality but I have no way to verify that.
Based on replies so far, I assume you are talking about for a vertical mill?
KEO might have something, not sure of cost though...
Asked as if its for a horizontal mill, best place I have found to buy those is EBay and none I ever bought were more than about $15 US, Moon, Niagara and Dolfa (?, drawing a blank, Polish...) my sizes were to work with a since sold Atlas horizontal mill, larger will be more $$$ but not double I would think...if its not too wide, I have also seen what used to be flat cutters ground to that double angle
A thread mill of the correct pitch does a fine job of that. You can buy just the inserts and make your own holder or get a solid carbide one. Then you can cut all the grooves in one swipe. It's way faster and less chance for error.
You don't want a 3/4 inch diameter DA mill. If you want to use a single point mill, those groove are in the territory of the 1/8 inch Onsrud carbide engraving tools spinning at 8-15k rpm..... and the tips are extremely fragile. I wouldn't on your machine.
The picture I provided is but one example of the serrations that can be cut on the flat top of a 1911 slide. Flat tops can vary in width and therefore the layout of the serrations. Also, there can be different depths of cut on some of the serrations to give extra eye appeal. Some also stagger the start and stop points, etc. Most use a double-angle cutter for this process.
