I have a Carvin Bolt-T. I like it an awful lot. It has very nice build quality. I will say this there used to a be knock against Carvin as far as resale value went. But that has apparently gone up. And also there are some whispers about some less then great customer service recently but I can't attest to it first hand.
Carvin keeps their prices down by only selling direct. Like I said before their build quality and materials are very good.
I hope this helps. If not feel free to PM me.
