I put in three sets of the IKEA wardrobes with sliding doors. Have to say I think they are fantastic value, literally 1/3 the price of something like Slidero es. You would want to replace the whole wardrobe though, not just the doors, but the car cases are not expensive. The IKEA builder tool on the site was great as well, you can build a full 3D simulation of the room, see what fits, add all your extras then click Order and all the bits and bobs arrive a few days later.
There’s a bit of effort to install them, but as usual lots of clear instructions provided and only basic tools required.It’s time consuming but well within the capability of a DIYer in most cases.
