Would love some advice!

I’m off to Thailand next month and I’m hoping to get my myself a reasonably portable vintage digital camera.

After taking I look at some, I’m thinking about going for either the Sony Z30 or the Cannon IXUS70. I particularly love the vintage, grainy look those cameras produce.

I wanted to ask, would it be a better idea to get a camera that runs off batteries than a rechargeable one, how long do these cameras last before having to change the batteries out?

I also wanted to ask if anyones got any other cheaper alternatives to the cameras I mentioned, considering they’re going for about £70-120
