We’ve not got that particular model, but I think all the Womanizers feel reasonably similar in action, and the price difference is more for the extra features. Mrs Chimp is a big advocate for the suction toys. 
If you’ve not tried one, then I’d say they’re definitely worth a go. Not everyone gets on with them, but as they work differently to regular vibrators they’re kind of a toy you have to try to find out.
There’s the Womanizer - did it work? topic for a general overview, and that has the latest comparison table in too. The starlets only have 30 minutes runtime (which is quite short compared to other models) but they can be a really fast orgasm toy for some, so that might not matter.
