Safety-wise, if you can trust yourself to always unplug it from the mains and short the big cap before sticking your hands inside, the risks should be not unreasonable IMHO.

And as ever with risky machinery, always work in good light, in an uncluttered area, and when you're not feeling tired.

But if you can't trust yourself to do all these things religiously, then yes, treat yourself to a new one.
