A few questions to help respondents to you:
1. Are you skilled at soldering?
2. Do you already know how to use a multi-meter and have understanding of capacitors, transistors, diodes, ICs and have other strong electronic skills and knowledge?
3. Are you willing to read a lot, watch Youtube videos, and learn about areas you don't know much about?
4. Are you okay if almost everything is working but maybe a few minor issues aren't working sometimes? Or only would be content if everything works 100% all of the time?
ST:TNG does have some fairly frequent repairs and maintenance challenges and can be difficult to get and keep working 100%. Depends on how much use and abuse of course the one you might buy has undergone. It's still a reasonably decent bang for buck pin and is quite fun. If you already have lots of skills from hobbies or from job settings especially re: electronics and mechanical skills it could be a decent first pin. And lots of folks here have lots of knowledge and advice available.
It would have been a terrible first pin for me to work on because I could barely solder and didn't even know how to use a multi-meter or which way to install a diode when I started in this hobby. Wishing you the best whatever you decide!
