That is truly a subjective opinion. I am not a big fan of ball machines myself. But this is the biggest and highest rated one so far. And it’s not half bad. https://www.instructables.com/id/CHAOS_Knex_Ball_Machine/

CHAOS ball machine is the biggest on this site, but on youtube, i found a knex ball machine 11ft high, 8 ft ide, and used 34,000 peices!!!
There is one on YouTube which is nine feet tall and used 42,000 pieces.
I went to the website of the guy who built that ball machine, and he has over 50,000 pieces! Even I don't have that much.
Yeah, how much do you have, then? I think I have around 7,000 - 8,000.
I have around 20,000 to 30,000 pieces.
If I wanted to build ball machines like yours, would it be worth while getting the Giant 6-foot Ferris Wheel?
It would be a great set (because it has no micros or bricks), but I would try ebay first.
I got my pieces through many years of collecting sets, ever since I was 5 years old.
I thought you were talking about instructables
I am, but i was just mentioning it :)
METROPOLIS is the best. BTW it used 97000 pieces
In my opinion, I think that Wipe Out and Twister are the best of the best.
I second that.
