I have the 6.5 gallon version of the Anvil Foundry. I was sold on the Anvil product over the competitors due to price point, temperature control range, size of the unit which fit my brewing habits (I do 10 liter batches), double walled construction, dual power input capability, and the Blichmann/Anvil customer service which is excellent.
The one thing I don't like is the location and ease of access to the control panel. If the face were pitched to face upward just a bit, it would make adjustment and operation a lot easier.
Right now, if I were to change anything it would be the head on the recirculation pump to allow for an exit valve to control flow rate rather than the hose clamp. I have not done any mods on it yet, and this would most likely be the only one that I consider.
I would recommend the Anvil Foundry if it fits your requirements. The controls are manual and push button. If you prefer having Bluetooth controls or the ability to set in an automated mash schedule then there are other, more pricey options (Grainfather).
My process is now well established with the unit after 19 brews. It took three brews to get the process down and figured out to my liking. I took another 4 brews to play around with my crush to get satisfactory results. Since then I have been cruising along and getting very consistent results. I had previously been doing BIAB on my gas stove (v. high output burner) and this pretty much now mimics that process without all the mess of moving the kettle and wrapping it with insulation for the mash steps. Having the unit full with water and automatically start heating after setting the delay, means I start mashing in sooner in the mornings when I brew. This is traded off with a lengthier cleaning process at the end of the brew session, so my net time is the same.
