Hi guys, In my opinion, shirk singletons if you can. I was using them too but I came across something called dependency injection and now I don't have a singleton in my code. And as a result the code is much better unit-testable.
Smartypants and legato-IOC are some frameworks you can use. If you search for 'alternatives to singleton flex', you'll find a number of articles telling you why singletons are bad.
