Loren,
I had bought one w/o the neck (I think it was Tamraz also) and after looking at it really close I wasn't really happy with it. I bought it off of Ebay and I think it may have been a lower quality version they sell.
I went out to Year One and bought another one with the neck and it's much better.
I've noticed that they have several tiers of quality and this is typically by price.
When I bought my tank from Year One, I also picked up the top pad, anti squeak straps and a new fuel sending unit. I wanted to make sure once this thing is mounted, I'm not tearing it back out for a long time. ;D
Supposedly my tank is treated on the outside and doesn't require paint. I've seen others that are less expensive without the coating that they say you should paint.
Hope this helps...
