Ive just checked, Scarpa still produce their Manta boot, but their not a cheap option.
By the looks of the photographs and reviews, the quality of manufacture is still there, but at £200+ depending on the model, their at the top end of the market, but at least the quality is still available if your prepared to pay for t.
Even the original style Vibram sole is used, making them a good option for the discerning walker looking for a boot that will last.
It goes to show, that if your still prepared to spend a sizeable amount on high quality gear, the quality of manufacture is still out there, but like all tried and tested products, quality usually costs a lot of money.
