I have to admit, I have not been interested in Transformers until like now. I had them when I was a kid and kindof just forgot about them. However, thanks to the wonderful people of /toy/, I needs me some transformers but don't know which one to buy. The last one I bought was the Starscream from the pretenders line(pic related). This was when it first came out. I need the help of my fellow /toy/ soldiers.

TL:DR What should my very first Transformer purchase since my childhood be?
