I'm just a beginner myself, but I've already gotten quite a few tops.
Considering shipping from the USA to Australia, it makes a bit more sense to go with something a bit more "high end". Of course, I do advocate starting with the Bearing King, but the bearings need cleaning, the crown needs taping and the string is too short, it's not an ideal starter. If the work doesn't bother you, then it's not so bad.
Honestly, the recommendation for the Strummol8 Gulia may sound like insanity, but it's probably one of the most ideal tops, period. Right size, right weight. While smaller and less expensive, the STB 2.0 is also really good, and I find myself really liking this top. The Sophina is just too expensive for a starter, despite me starting with that as my first expensive top purchase despite not knowing how to spin tops yet. I ordered the Sophia in early October because I decided "it's time to get into tops". I did most of my learning on the Gulia. I think my modest success is due to this spin top.
The prices are kinda up there.
I find the Spintastics Trompo Grande or Trompo bearing to be a bit too big to start with, but the price is really super affordable and I find them to be a good top. I find the Blizzard and Gladiator to be too small for starting, and they also spin with a lot of energy and so they can be a bit much to control immediately on a boomerang.
I feel the Chico Delrin spin top is just too expensive for a beginner, but if you want an easy to throw top that is easy to control, then it might be a good way to go. For roughly the same money(OK, about $5 more) is the Strummol8 Sophia. The Chico Spin Top 2.0 took me a bit to get used to due t the tip, but it shouldn't stop you.
If I was starting out, and knowing what I know now and the person has decide to make it work and is willing to spend decent dollars to get decent equipment, I'd say the Strummol8 Guilia or the STB 2.0. If you're serious, you can justify the expense. These are just amazing tops, not just for learning, but for whatever you want to do.
I am also only speaking of models I am familiar with(that I own).
