I use prefolds (Tommee Tippee) and I have found these to be fine so far. They come in three sizes with booster pads for night. I don't have a tumble drier either,but find that they dry on an indoor line in 24 hours or less - TBH so far I have only had to dry them inside a couple of times, but with winter coming it may be more frequent. I reckon even if we have to buy and use a tumble dryer, it will still be loads cheaper.
I have heard the same with all in ones, that they take longer to dry as the waterproof layer is attached. A friend of mine now uses stuffables as her son is 7 months and crawling - these look easier to get on in a hurry. You can get sample packs though, so if you are unsure, buy a few of different types and see which fit in best.
Good luck with everything!
