Finish Sander? ROS? Reviews are confusing so I need some advice

I was looking at BeginningWoodworkers post about 1/4 sheet sanders and wanted to ask a similar question from a different angle.

I do mostly small items such as boxes, cutting boards, etc. I have a stationary belt sander for the flat stuff but have a need to get into corners and to soften rounded edges.

I tried the Black & Decker Mouse—Big and Dumb mistake. The mounting pins liquified and the machine fell apart. They have a local repair shop but is about 25 miles across town. I’m not sure driving over there would be worth it. The performance while it lasted was pretty good for my purposes. The shape allowed me to get into tight spots and really round out edges.

I also have a Skil Octo. This has been my machine of choice even though it looks like a battle scarred veteran. The hook & loop surface has tried to peel off numerous times. I have been able to glue it back a couple of times but not much longer. The sanding platform on this machine broke loose but I have been able to hold it together with a very large rubber band. The rubber band is the only thing holding it together. The dust collection is just plain bad. I sand next to a sweep on my table top that hooks to the DC system so I can keep it down to reasonable.

All that said, I need to find a good finish sander that can get into tight spots and last longer than a month or two. It doesn’t sound like I’m asking a lot but apparently I am.

The ROS (Makita, DeWalt $50-$90) I have looked at all have the round surface that isn’t really conducive to getting into tight quarters.
The Bosch system ($130) with the triangular head looks a pretty good but they have a history of burning up their motors. And does the shape of the Bosch wear you out after a while or is it user friendly?
The Fein system is well reviewed but is in the area of $350! It has a similar design to the Bosch with the triangular head and can be adapted to be a cutter, saw, etc.

OVERLOAD!!! I could use the voice of reason and experience here. I’m open to any suggestions anyone may have. Thanks ahead of time.
