FYI, I think that Sarasa Grand pens are very nice for around $10. (I took mine and replaced the color ink with a black Acroball refill.) Energel Alloy pens aren't bad either.
I also have this no-name brass twist pen sold at Amazon (I have a company logo version) and it is solid for the price: https://www.amazon.com/gp/product/B0BKZN1JTY
