Matt,

Nothing wrong with the HHA moveable sights. They're machined very well and as good as anything in their class.
The SightMaster series are excellent also but somewhat expensive. I have the Elite 2000 with the accessory Micro Windage Adjustment.
The Sightmasters have, probably, the widest range of adjustment.
You can tell how much of an adjustment range you have on this type sight by looking at the scale at the rear of the sight.
The wider it is the greater the range of adjustment.
I have settings to 120yds. on my Elite 2000 for practice at long range.
Toxonocs makes a rugged unit too but it doesn't have the adjustment range of the Sightmaster.
Bullseye Sights has a version out also that you can use with their scopes.
You are right, if you get one you will have to compete in the open class against the guys with the Sure-Loc's, HTM's, CBE's etc.
If you can compete against them and beat them with an HHA, you will have a bunch of Pi**ed off 3-D shooters to contend with. LOL.
http://www.fsdiscountarchery.com has pretty good prices on them.

Good luck in your search, Matt.
