Opinions on Baird and Cashman Round Pens?

Looking for round pen panels in the Northeast. I only need 6 panels, which is tough to find in my area. I can get 8 at a good price from Baird or Cashman. I saw one person on COTH has Baird and is happy,. I have not found opinions on Cashman. Before spending pots of money, I wanted opinions. I could get the Noble shipped here as well, but Baird and Cashman are made closer to me, so shipping is cheaper. I can only get a full round pen of Priefert, and I don’t like the design quite as much. Other suggestions welcome.

TIA

Don’t get the round pen’s with the rounded edges on the panels that make a “V” between panels, they aren’t safe unless you find a cap to put on them.

If Baird is Chubby Baird, I had his 80’ round pen. It rusted, not bad but they did rust in the humidity and the gate didn’t hold up but the price was reasonable especially with shipping but the “V” between the panels should be addressed.

I believe it is Chubby Baird. The two pens that I am looking at right now have square corners:
