I've seen a few people reference the 4047.....which is one of my go to vocal mics. I also use a KSM32....which is a very clean mic.....but as someone else has indicated it is so transparent that it can be too good for a weak vocalist....although it can work very well with a good vocal.
Before I spent $1,000 on a mic (there are soooo many very good mics in the $400-$600 range) I would also look at my signal path. You don't mention what pres you use.....but a $1000 (or even $600 mic will be less effective is the pres are not decent.
