I'm not really clear on what you are asking... so I'll just give you my experience.
I bought a Push/Pull spinner from Oscar. It is a solid spinner... it has very little wobble. It's nice and heavy, so you don't get the flakey controls of some of the cheaper/smaller spinners. It works awesome for DoT and Tempest.
It's not exactly like the Tempest spinner (because of the push/pull nature, requires more room than almost flush of the Tempest spinners) - the knob I have has no skirt either, it's more of the oval type. My biggest gripe with the Push/Pull is twofold, and neither affect Tempest, only DoT.
First, the push/pull action is a little mushy, I'd like it to be more crisp. Secondly, the pull in DoT only activates AFTER the circuit cycles, as opposed to when the closes. This may be an issue in DoT and not the spinner itself, I haven't checked yet, as I only noticed it last night. Aside from these two very minor flaws, if you want to play both games (DoT and Tempest) w/ one spinner, the Oscar Push/Pull is a very good choice for this.
If this isn't what you are asking, then I apologize in advance.
