The company I work for sells the Goodridge brand "Speed Bleeders". That's what I used and (aside from the too-deep ports) I never had any issues with them. The 3/8-24 version is 1.3" long overall, so you'll get a little extra reach.
Some brands look like a modified bleeder screw, where the seat is a separate moving part and you can see the spring connecting it to the rest of the screw. The trouble with that design is that you now have two sealing surfaces to worry about -- the one at the seat, and the one between the moving tip and the rest of the screw. In the unlikely event of failure, the screw could fail to hold pressure. (On the plus side, that's almost certain to show up while bleeding, not while driving.)
The Goodridge design starts with a standard bleeder screw, then adds a one-way valve inside. In the unlikely event of failure (let's say the valve sticks open), it will still operate just like a regular bleeder screw. Worst-case scenario, if the valve sticks closed, you just won't be able to bleed the system. Neither failure mode has the potential to make the system fail.
I did find that it's worth cleaning the screws after bleeding. Just a quick blast of brake cleaner aimed inside the screw will flush out remaining fluid, which in turn will help to ward off corrosion. I replaced my bleeders after 4 racing seasons, just because they were looking grubby. They still worked just fine, I just figured that if they looked that bad on the outside then surely the insides weren't any better.
And just in case anyone wants to jump in and say they don't trust EZ bleeders at all, there's another one-person option: We also carry a bleeder bottle which has a one-way valve in the hose. Works the same as the fancy bleeder screws but you don't have to give up the old-fashioned bleeders. The only thing to be aware of is that the Goodridge Speed Bleeders have a sealant pre-applied to the threads, to prevent air from sneaking in around the threads when the screw is opened. With the one-way bleeder bottle, there's a chance of getting air in around the threads. Still, it's good for doing at least 90% of the job. You can easily get it to the point where your helper only has to push the pedal once or twice. (Again, I've used this solution and had no issues at all, didn't even need to follow up with a helper.)
