That setup should serve you very well for a long time to come, great choice!
This is true, but I'd avoid the ti nail

I don't recommend dabbing on titanium at all. TBH, better dabs can be had with a cheap quartz banger and a torch than a titanium enail!
I couldn't agree with you more about the benefits of the Auber purchase over DHgate options for the money though

Definitely a sound purchase for that additional peace of mind.
That'll work well until you get your hands on a SiC enail. As above, torching a quartz banger can still be tastier than titanium enails, so long as you've got your torch technique and timing down

As I say below, keep your dabs small when torching a quartz banger. The bigger the dab, the more waste!
Definitely try out the quartz nails man, I'd avoid the titanium because of inferior taste and the need to season titanium nails. Do keep in mind that the SiC enail experience is incomparable to torch dabbing on quartz, even when you've mostly dialled in your torch technique. A SiC enail will give you delicious, consistent and efficient dabs with voluminous clouds every time (think sublimator level clouds) and minimizes waste of your dabs.
I frequently shudder when I watch people torch dabbing on quartz, so often I can see a visible pool of unvaporized resin leftover in the dish which they just qtip and throw away!
One big tip for torch dabbing is to keep your dabs smaller (.05g or less). This is because larger dabs may not have completely vaporized by the time your nail has gotten too cold otherwise. This means wasted dabs. Alternatively, with larger dabs and a torch + nail, you can just overheat your nail to compensate, but this will ruin the flavor and make your dab super harsh instead.
