Golden Tube SE-40 - Worth screwing around with?

There is a nice example attractively priced near me. Sonic Craft had an upgrade kit for them, and it sounded like a fun soldering project. The reviews I’ve read seem to be “Flawed design, doesn’t meet specs. Sounds fanatic though.” I’ll be ok as long as I can get 20wpc out of it at least

What’s your opinion on the brand/model?
