I purchased the EST EC 125 because I like that size and have a RO125 which allows me to share abrasives. I am making new cabinets and have thought it might be worth it to have the larger size for all the sanding needed for doors, panels, shelves, etc.
The many discussions on this on FOG which helped sway me to sticking to the 125 form factor.

Unfortunately it's the other way around - the 150mm pad fits on the 125.
