For tube mechs, I preferred the Greek mods.
Gus makes beautiful mods that haven't been cloned and are not only available, but affordable. The only tube I ever regretted getting rid of was my Gus.
Next is the Atmizoo roller. I've seen similar "clones" of this but nothing even comes close. Fantastic design, flawless finish, brilliant threading, and a button that is second to none. I miss this one on occasion as well. Also, the Lab. In stock, fairly priced.
And then there's MMV. Makers of the Poldiac, Temon and DID. Poldi has been cloned, but they all seem to be plagued with issues. The Temon was my first mech and I adored it. Poldiacs are gorgeous works of art that perform amazingly and can be purchased at this very moment in several variations to suit your taste. A few months back they were selling the Poldi V1 for $100 and you could even get it engraved for free.
Agree. Gus and GPs are not going to be cloned easily and correctly. The GP and Gus switches are out of this world. Too complex and smooth for China to tackle. Their customer service is also not matched.
If you find a 2.5 paps in good condition I would buy it. It will make others look like trash.
