I'm looking at the same type of tools as you for ETL or ELT, depending on your methodologies, and needs. Robustness is a key issue as is price for me. I am beta-testing Maestro and like what I see so far, but as noted you might need more robustness with the product.
Alteryx is definitely a consideration, however the subscription price is too much for me. I am now looking at FME from Safe.com: FME Desktop | Data Integration & Productivity | Safe Software which allows for a free trial and is not subscription-based and appears to have most of the same tools as Alteryx.
It might be something for you to look into...hope it helps, Don
Thanks Don, I had not heard of FME/safe. Their website design looks familiar
You can try Prep for free for now so you might give it a try.
