There's a world of difference between the Vintech unit and the ones using the stock plastic casing.
In comparion, the stock unit looks ridiculously oversized, cheap and faux-retro. (No surprise given that it's part-binned from the guady 'Bolt' model.)
The Vintech hits just about the right note, in harking a little to the past with a nod to the future (by way of the halo ring effect of its running light).
Money well spent in my opinion. (Especially since it looks fantastic fitted on a minimal tail tidy and with rectilinear indicators - photos pending...)
