Anyone been to (little) Koh Chang recently?

I'm looking for a nice and peaceful place to relax and study for a month or two. I was looking at the wikitravel page for Koh Chang (Ranong) and saw that the bungalows are only 150-250 a night, is this true?

I'm just a little incredulous because I visited there for a few days about 3 years ago, and remember the cheapest place being about 250 a night. Falling prices at Thai beach resorts is a strange phenomenon indeed, although there do seem to be a lot more guesthouses listed on the wiki travel page than were there when I last went, so maybe increased competition hascaused the drop in prices.

So do you think I could find a little shack to rent for 5000 a month or under? If things are anything like the last time I went then the huts will be tiny bamboo things, where the only electricity is in the resort restaurant (and that for only 3 hours a day). I've just spent the last couple of weeks working in the Australian outback where we had to take a shovel into the bush whenever we wanted to take a toilet, so this will seem quite luxurious in comparison! I actually found that I quite like the simple life (minus the thousands of flies an mozzies).
