Recommendations for social sharing buttons

I’m having trouble finding a good social share buttons plugin that has all the features I want. Maybe none exists or if they do they are outrageously priced. (I saw one for example that might do this but it was $250 per month!).

I would like floating buttons, buttons above or below the post content (or both) and both like/+1 and share buttons. Also the floating buttons should collapse or do something to make sure they don’t screw up the mobile experience. It seems nothing free does this and looks good.

The closest I’ve found is monarch social share but the downsides are, it costs money, it doesn’t seem to have both +1/like and share buttons and it has a stupid design where it has to load something from the /wp-admin/ directory making it impossible to add common sense security measures like denying public access to this folder. Still this is the best I’ve found in terms of looking good, working well and having a good user experience across all devices.

What else is there to look at?

Thanks.
