Normally Eprance is a good option as long as it is via Amazon and not direct from China.
Since you are in the UK,
https://joovuu.com/gb/home/106-mini-0803.html is an option, although they don't seem to have a 0801 and the 0803 is currently being replaced by the 0805 so buying an 0803 today would give you one of the last of that model and I guess it is a bit more expensive than you wanted anyway.
Buying direct from China is risky due to the cost of sending it back if there is an issue.
I'm sure there are other options...
