If you don't like it..... don't buy it! If you don't like the way it looks... don't buy it! No reason for you to be in this thread.
Mass-market vs. "high end": increasingly, these days, maybe for a while now, the difference in physical parts quality is almost zilch. It's not like the days of old where you're paying for hand-matched transistors, top-end small-quantity Burr-Brown DACs, etc. etc. The _physical_ difference between synths in terms of quality and reliability is not a factor.
What you get, when you pay $8,000, or $4,000 for that matter, or $3000, is a level of R&D investment in custom design, and perhaps even more importantly than that, and the innovation that comes with it, is "after-sales support." The latter means stocking inventory to make sure what's sold has the parts needed for future repairs, if needed; that the expertise is there for repair and tuning and the like; that the company that has sold the instrument is as committed to it for the long haul as you are.
Beyond all that, it's more a question of variety and depth of capability than absolute sonic difference per se. Less expensive synths are narrower and more targeted in focus in terms of what they can do, are more likely to be "throwaway" (no further support after 3-5 years after sale), may have a look or feel that says "less expensive" in current terms (plastic rather than wood or leather, cheaper plastic rather than better plastic, etc.). They may re-use a common bin of parts rather than have more specific parts sourcing for their production and support. They may have a smaller support team and less training in support and customer service post-sale. All that stuff.
Anyways, to me, they all sound great! Priced high, or low, of whatever seeming quality.
But, just as I wouldn't knock a high-priced item for its price, neither, these days, would I knock something more mass-market in price. The results are basically astonishingly good, either way.
