dutchy101 RO without remineralisation won't be near zero TDS unless you use a DI post filter.
RO without any remineralisation will likely produce water with too little mineral content for anyone other than Decent espresso users.
So RO, with remineralisation would normally be the way to go, but get a drop kit in any case as you can then monitor/adjust as necessary (either by reducing the alkalising filtration, or adding alkalinity yourself with sodium bicarbonate to the filtered water to achieve around 40-60ppm alkalinity).
