The flash bracket / umbrella swivel I'm using works just fine, but I'm a little nervous about the way the flash attaches. It's held in place by a combination of friction from screw on the side of the flash bracket itself plus friction from screwing down the wheel on my flash's shoe/foot mount.
Since the bracket is metal and my flash is the older Metz 48 AF-1 design, with plastic foot, I feel a bit nervous about clamping too tightly. But if I don't, it seems like there's a risk of the flash just sliding right out either the front or back, especially if the bracket gets tilted.
Is there a better little cold-shoe product that's less scary? I'm not aware of anything which has the Pentax-specific locking pin slot (except this which is out for price), which would be a little comfort, but that's not necessarily the right approach either. It seems like there ought to be something where there's a secure latch on the front and back, so once mounted the flash can't go anywhere (but which could still be easily undone). I can't find it, though. This accessory shoe at least has the front blocked, which might be an improvement, but on the other hand it lacks the side friction screw.
Does what I'm looking for exist? (Ideally for under $20, shipped. I know geegaws like this end up being outrageously priced.)
