A bit of shameless self promotion! I've got an extra copy of Wong's book that I'm selling on eBay. If you're interested, check out : http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3577671260&category=2239&rd=1 I also have a couple of Uston's books that you can see by Viewing My Other Items from the listing. Thanks!
