Personally I wouldn't bother. Open up a 58, or even a 56 and you'll still be able to get the "lofted" results you're after, admittedly it needs a little practise 
I had a lob wedge for a while and (for me) it was a wasted club. The instances where I needed to lob the ball up in the air were so few and far between the lobber didn't justify it's place in the bag. To be honest I tend to find that the majority of the chip shots I leave myself are better suited to 'bump and runs' with and 8 or 9 iron. They're also much easier to execute than a mickelson style lob shot.
Just my 2 penneth.
