NB - Hardtop or new Roof?

I've had my 1999 NB for nearly a year, having purchased it off the original lady owner. It had covered only 38,000 miles when I got it, and it is in lovely condition. My dilemma is the original roof really needs replacing and can't decide whether to replace the roof with a new one or find a secondhand hardtop.

It seems the going rate for a new roof is slightly cheaper than a secondhand hardtop, not withstanding the fact I'd probably have to have it painted.

What's people's thoughts on hardtops? The car is my daily driver so is used during the winter.
