Need advice on sliding mirrored closet doors

We are replacing closet doors in 2 small spare bedrooms and want to install sliding mirrored doors to visually enlarge the space. We did the same thing to another bedroom 30+ years ago and have been very pleased (see photo). Those doors were from JC Penney and are no longer available. We looked at Lowe’s Reliabilt doors and Home Depot’s Contractors Wardrobe and were shocked by the price difference - hundreds of dollars per door!

Does anyone have firsthand experience with either one? I know you get what you pay for, but what is the difference? Specs look the same, doors are not available for viewing in store, and salesmen were clueless. Hubs wants sliding rather than bifold. Any input there?

thanks for any tips you can give as to preference or what to look for.
