Salt Flats (Uyuni) Recommendation

Hi all,

Hope you're well! Looking forward to my upcoming trip to Bolivia in October. Will be looking to do a 3-day salt flats tour and was wondering:

1. How much should I expect to pay as a 'good' price? I've seen extremely differing prices from different people, so would be good to have a perspective of what's normal.

2. Does anybody have any recommendations for operators? I'll be in La Paz before, so I can go into offices if that's helpful.

Thank you so much in advance! Any help is much appreciated.
