I might take the plunge. I can get one for $335 (b-stock).

Like this... but black...

How does this rate in the 7 string world?

I have an Blackjack ATX hardtail and that neck is fine for me. Is the profile similar?

I have the C-7 hellraiser and i love it! It plays really smooth. Sounds great and handles the low tuning really well. The neck is wide because its a 7 string but i really love mine and wouldnt part with it for anything.
Go for it, worst thing is you dont like it and could sell it like new if you keep it in good condition, and make a little money
