Thanks for the posts here. I ended up picking a SpriTech from Amazon over the holidays. My first fill-up made me grateful for not spending more, but my more recent experience has me doubting. If all you are doing is filling up a partially filled gun this is likely a fine unit. If you are filling up a Ninja 90 bottle from 2000 to 4000 it takes everything it has, with an 8 min rest in-between two sessions. And its loud. The fans are loud. The little pump that could is loud. Something to consider if you live in a busy house with sensitive types.
