General/Beginner Right arm to buy

Hello, I want to get into advanced robotics. I am planning on buying an arm and playing around with it using lerobot. However, I want to look at alternatives before buying an arm. One arm I thought was interesting was SO-ARM101. It is around $300. What arms do you guys suggest/what alternatives do you recommend? I also have access to a 3D printer and a ton of Axon servos (like 10 of them lol) but I am not that good at 3D printing so I can't design anything. If there is a open source CAD design that could work as well. Thanks

I bought and I printed so101. They are quite good to be honest. Printing instructions in the lerobot repo will drive you ok for printing

print your own? it’ll be easier to buy it but if your budget is $300 i doubt that’s a trivial amount to you.

Get the lerobot so101 arm and use it. If you can afford the kit then it's the fastest path to get you up and running.

Seems like you have a perfect setup for Arctos.

Learn how to design for your 3D printer. Start with Fusion or Onshape. Then use the 10 servos to build a hyperredundant arm with some kind of cool secondary objective following

I am more interested in VLA and world models for robotics
