HAPP 3" Golf Trackball

[Sinner]

Is there something special about the HAPP 3" Golf Trackball? (PT# 56-0100-11HL)

Does it differ from the regular HAPP 3" trackball?

Our local supplier has these on sale for $65CDN.

I bought 2 of these back in March (I presume you're talking about the Starburst sale at $65) and the only difference I can see is that this version has a "collar" that can be removed to alter the height of the lip, depending on the thickness of the panel being mounted to (different versions of Golden Tee have different thickensses of panel).

Other than that, they appear to be the same as std Happs 3" ... I installed the Happs PS2/USB adapter & optics in one without any trouble.

I thought they were an exceptional deal ...

Cheers,

There was a thread a week ago that stated mechanically there is no difference.  The lip of the golf version is the same height relationally to the ball as the whole top is on the regular one.  By lowering the plastic cover everywhere except the lip, you essentially get another 1/8" +/- height of the ball above the control panel.

If that doesn't make sense, do a search to find the thread - there are pictures of the difference.
