As David said, don't confuse throat depth with cutting height. The older 14" Deltas came with a standard 6" cutting height but an optional 6" riser block was available to add in the middle of the column that would allow it a 12" cutting height. I have an 18" with 12" cutting height. If you plan on doing more scroll type sawing then a smaller saw is usually good as they are geared for narrower blades which cut tighter arcs. If you are mostly resawing then bigger is better so that you can use wider, more aggressive blades with deeper gullets and fewer teeth per inch.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
