I would take the plunge on it. Not a major Trek fan myself but it's a great game. Better than the newer stern one, imo. A somewhat more complicated game for your first can seem intimidating but its totally worth it because it's only downhill from there (my first dis/reassembly was a WH2O...damn that sucked).
Actually, i have another friend who's considering a STTNG as his first pin right now as well, so that's the same advice i gave him.
