Price for that L6 sweetheart? How about cheap to me and around $350 for everybody else?

Actually, $350 would be the range I'd expect to see this one in.
Size, method, and maker can make a difference in price. Larger knives (requiring more material & longer concentration to make), forging (vs stock removal), fame of maker, or fancy materials can raise the price. For a forged blade, don't forget to include the voodoo magic factor when justifying a higher price to a potential customer. Sometimes how you sell it is more important than what it is.
As for the design of this knife itself, I like it overall. There's lots to like in the knife IMHO (material choices, fit 'n finish looks good, size of blade (looks like about 7.5" or 8"), recurve edge for chopping, robust tip not inclined to breaking). As for what I'd change, my preferences line up with Wulf's -- smaller guard and dropped handle.
I also prefer guards that tip forward at the top for two reasons.
(1) In the usual "thumb braced on top of the handle" grip used for a draw cut, the ball of the thumb falls naturally ahead of the rest of the fist holding the handle. Having the guard canted forward at the top of the handle gives room there for the thumb and facilitates this grip. Having a very small (or non-existent) top quillion on the guard is also a good thing to me.
(My knife uses are civilian utilitarian, not combat/fighting so that biases me away from blade-stopping size guards.)
(2) IMHO a guard canted forward at the top helps a viewer's eye to flow along the knife. A physically prominent guard at 90-degrees (right-angled, as this one appears to be) to the handle tends interrupt that visual flow, as does a visually arresting guard with strong colors or pattern on an otherwise plain knife. A smaller or canted guard will create less visual obstruction to the visual flow of a knife design. However, to show the exception to this, consider the wonderful flow that can be achieved on some S-guard bowies where the massive guard is easily the most prominent feature of the knife. But the shape of the guard eases the viewer's eye over and across the knife.
That's my $0.02, so YMMV.
