All of us were new at some point, so give the guy a break. Alan, you'll learn over time that everyone here is so different and wants different things, that a 'pick which one' thread will get you answers from across the spectrum. The knives regularly discussed here are all great for their own reasons...eventually you will know your needs and wants better after gaining experience with more knives that will help to specify your questions.
Just relax and take it slow, and realize that most knives you will be able to sell if you don't like them for a relatively small loss. Keep asking questions though, otherwise it gets boring around here.
To the OP. It takes everyone a little time to sort of find their bearings in the knife world. It might seem a little confusing at first, but keep at it. A year ago I had one knife and now I have about 15. Give it a little time, perseverance pays off
To the OP, don't stop posting. All questions are welcome, even if it has been covered many times before. The least we can do is direct you to another thread. I've asked a lot of what knife to buy threads in the past, I think it's an important part in learning about all the different choices. To answer your original question, I'd go for the Martell foremost, then the HD if you're impatient. You can always get the HD rehandled down the road if you want it to look pretty. I'll even add a new contender for you, 300mm CarboNext sujihiki—least expensive.
I think the Hattori FH has the best F&F (fit and finish), and in my opinion the Konosuke HD has the best steel, based on my experience with other HD knives. I haven't any experience with or opinion about the Gesshin Ginga, so it may well be the best of the four.
Muddy water is best cleared by leaving it alone.
