Felixflyer,
Heres some advice, ignore most of what you read on these forums. Research by other means and then do what suits your circumstances best.
You can spend ages messing around in GA trying to network your way into a job, but you soon realise the pay cut you've taken over twelve months is more than the price of a rating.
The right speculative rating can be a way to employment, between 2005 and 2007 speculative ATR and 757 ratings were a very good way to get employed.
In the current climate jet rating alone is unlikey to get you employed, but a rating + line hours? The employment rates are better than some of these forums would suggest.
