Some thoughts on words and standards:
"Authentic" and "traditionally made" will mean getting an antique and not therefore under $500. A decent reproduction under $500 will be made of steel, cut from a blank, and formed using stock removal by grinding. These are not traditional Bronze Age techniques. Handmade, yes, but then Timex watches can be said to be handmade in that they aren't assembled by robots.
Taking the wristwatch analogy further, no traditionally made Swiss mechanical watch of the highest quality and finest craftsmanship will ever keep time as well as the lowest tier Chinese-made Timex quartz. Likewise, no genuine Bronze Age sword will be as "functional" or "good quality" as as a modern carbon steel reproduction sword (this is hyperbole--there are some crap repros out there, but my point is that modern steel would amaze the ancient smiths).
So what is it you're wanting? Wall hanger? Sharp for cutting? Blunt for HEMA? 20-yard acceptable looker for reenactment or cosplay? These categories matter. "Quality" is a marketing term. What you want to nail down is what qualities you are looking for in your sword. Good fit and finish are nice to look at and feel, but in the ancient world our modern standards were nearly impossible to achieve.
One possiblity is to place an order, handle the sword, and if you don't like it, return for a refund. It'll cost for shipping, but you'll get hands on experience of what the reproductions feel like and you can become the expert you are looking for.
