I got mine on eBay, as have a couple of friends in the last 12 months. Might need to wait to get a deal, but they do pop up. I didn’t wait long for mine.
I have both actually mju I / II paid £10 for the mju I and less than £50 for the mju ii years ago. I think the most expensive camera I have was £60 for a bigmini 201.
Cheapest mju I I've seen was £70 on BIN a few days ago.
I do agree about an automatic slr something like a canon 300x and a 50mm.
Where are these £30 mju I? Could do with a spare before prices rockets even more.
