Back from a 10 day trip or so a few weeks back - yes, highly recommended! A trip report will be forthcoming soon ish ... Basically a full anticlockwise circuit - mostly birds but fantastic scenery and some good cetaceans too.
Presumably you've checked out the reports on here from a year or two back? http://www.birdforum.net/search.php?searchid=14970052
Edward's website/facebook page will have further info/updates, and he may have recommendations.
Cloudbirder is also good for trip reports. http://www.cloudbirders.com/tripreport
If it was a driver/guide at a basic rate you were interested in, I'd probably be very tempted to make the return trip ...
