Again, I will be the "Rain" on everyone's parade!
I really like the hydraulic drivers. Especially when doing numerous holes, working heavy material, or working with stainless, the hydraulic drivers make the job a lot more pleasant!
That said, EVERY hydraulic driver I've ever seen has been a company-provided tool. I am sure the price was part of the reason for this. I would be afraid that any such tool, found for sale used in any medium, would be a stolen tool.
When there is such a doubt, I will not provide a thief with his market.
