I love my v4. And, while it overall doesn't give you any major difference on the end result over the v3, it does so happen to have some design changes that do indeed add some improvements. An all in one design without a separate trickler and being able to run 3 unmodified wind shields in nice. The double tube design means it can run any powder without any issues of getting caught up on any kernels. It's very easy to dump powder back into the container too when you're done. There's only one hopper to keep filled and pour out when you're done, which also reduces the footprint on your bench.
The main reason Adam MacDonald changed from the original design though was so he'd be able to keep up with the demand. He can make this version easier and cheaper, plus quicker, and without part availability issues (it has less parts overall).
You're also getting peace of mind with it, and both the dispenser and scale (balance) are extremely reliable. It's worth putting down a deposit and saving up for it. The autotrickler and Giruad bench trimmer are two of the best pieces of equipment on my reloading bench that would be extremely hard for me to part with.
I know it's not what you were asking about, but figured with many others posting about it, I'd post my thoughts as well, whatever it's worth.
