Given the relatively low cost of IMC capable kit nowadays, and the possibility of unplanned need to fly IMC, it would be silly (IMHO) not to go for a decent fit.
I would rather fly illegally but appropriately equipped than figure in an accident report through lack of useful kit. And if I had the kit, I would make sure I was trained to use it, and current.
Unless you are a purist restoring a vintage aircraft....
