Ask Amadeal? If nothing, ask them for a sensible referral?
Arc option is likely good, but depending on your location, collection from the other mini-lathe suppliers might be of benefit to the wallet. Personally, I might check out Arc, Warco, Axminster, Chester, etc and choose one that appeals, or is close enough to collect (if the cost is important). Google is likely your best friend.
Other options might be ebay, gumtree, twitface marketplace. Likely not new, but depends on what you actually mean by ‘off the shelf’.
