@GoldenBud Be aware that most of these cheaper d020 and matrix sidecars being listed with "-S" designation are slim cans ie 50mm vs 60mm wide bodies.
Personally I would just save up the 10 bucks and go with a Matrix Sidecar. Mid 30s tier chinaglass in my experience can be really good thick pieces.
The better matrix perc alone imo is worth the price difference let alone the bigger diameter and thicker glass.
While I do enjoy my D020-D I am disappointed that it is not nearly as thick and stout as the rest of my matrix chinaglass collection and the perc has probably less then half the amount of matrix cuts as my other pieces. (BTW People state that the older D020-D used to have a better perc...)
If you really have to go with d020 style neck for mid 20s I would look at the GB-223.
Its got a 60mm can but a pseudo styled matrix perc (ie very very few cuts, less cuts then even the D020-D...) but hey at least its better then the non D regular d020...

Note I don't own this piece. And I have never ordered from the Yingmin store. But I have ordered from lumin88 and sunshine store which I suspect might all be the same seller or come from the same factory at least. But I do know Yingmin is a trusted store by many here.
