Small batch kegging options

[ModlrMike]

I typically make 23L batches, and then transfer into 19L kegs. The remaining 4L I will naturally carbonate in bottles. Instead of going this route, I figure I could get a small keg and that would solve the issue. In addition, I could use it for small batch experimental or seasonal brews.

What are folks using in a similar situation? I've seen this keg on Amazon, but I would like some further input before I pull the trigger.

I don't see why that wouldn't work. That looks just like the Cannonball keg that Northern Brewer sells and it has a bunch of good reviews.
