I have always found PSI kits to feel and look a bit cheap. Their newer, high-end stuff, might be good, though their love of adorning them with pimp stones has kept me from finding out - where those kits are concerned. I have done the Broadwell Art Deco, and I do and don't like some things about the design, but the overall execution did have a bit of slop in it.
I did just do a Princess Pen with Hut's white micapearl for an order this last weekend and I can't say I'm pleased with that kit at all. The spring loaded clip (which I normally like) makes it top heavy and it looks tacky, tacky, tacky. I would never have made it, if it hadn't been ordered.
Honestly, if I have a quaility piece of wood or material I will always think CS-USA, or occasionally Berea, first. The Statesman (reg or Jr) is my go to kit, and Berea's Gold Ti and Sterling Silver finishes are a cut above when the use of them would fit the material.
In the end, what matters is does it sell, and if people are doing well with PSI kits, more power to them.
