Sayadaw U Puññanada is I believe almost totally unknown from westerners, and so far he is rather popular in Malaysia and Taiwan among the Chinese people who are shifting back to Theravada buddhism.
I was told that he mastered the Pa Auk system in two years (which would imply that he his at least a sotapanna), but somehow it didn't work well with the Pa Auk Sayadaw, so he had to go his own way and now he teaches on his own. The thing is, he has the reputation to be a much more talented teacher than the Pa Auk Sayadaw himself (which, knowing just a bit how burmese culture works, would explain the split..).

There are a few reports of (very talented!) lay people reaching the fourth jhana in no time (just only a few days), and that they started remembering their past lives as well.
Where knowledge ends, religion begins. - B. Disraelihttp://www.buddha-vacana.org
As a sweet-smelling and beautiful lotus flower may grow upon a heap of rubbish thrown on the highway, so also, out of the rubbish heap of beings may appear a disciple of the Buddha, who with his wisdom, shines resplendent in wisdom. -/ Dhp 58-59
