The 230V version is available now. Only the 110V version is not in stock.
There's a bug in your site. When you search from the search box and click on the link, it takes you to the product page with 230V selected but it says "Out of Stock" and if you choose 110 then choose 230 again then it shows in stock. So I didn't know they are in stock if you hadn't told me this and it's still requires effort to order them. Maybe you need to check this as probably most people are thinking it's not in stock.
