If your heart is set on Noto's would it be possible to obtain the relevant permits and collect some efts or even larvae yourself? At least that way you aren't supporting mass collections for the pet trade, and hopefully the animals you collect won't be on death's door due to months of incorrect care while in transit and at pet stores.
There were a lot of eastern newts imported into the UK a few years back and I don't know of a single one that's survived, I didn't buy any, but I know a few people who did, and even with the correct care they all died, sometimes for no apparent reason, seemingly healthy, active and feeding one day, then dead the next.
