I've been looking at this a bit more closely:
The Eagle X-TS became the X-TS 100, then there was the X-TS 150A and 150B models. The 150B is the current production model built by CTRM in Malaysia. I can't see a lot of exterior difference between the 100, 150A and 150B...I went with the 150B (now just called the Eagle 150B) as it had the most powerful engine...but the nose does not look quite right. So still looking!
