I had a Millennium plastic Astra that was great until it beat in. Then it was a roller. I don't usually throw rollers, so it belongs to someone else.
I bought a used Sirius plastic Astra that had the picture of Selah Ranch on it. It was already beat, so it was not of use to me. It's gone too.
In a nutshell, I like them when they're new. That said, I'd recommend a Quantum plastic Astra if you're going to buy one.
