I've had a few over the years.
Galfers: Rust on the banjos, Galfer was great about replacing them but the replacements rusted too.
Russell from Yamaha: Okay, odd fit, typical terrible Yamaha customer service, but they are cheap!
Fren Tubo: Very nice quality, can get them custom made, wait time is about 2 to 3 weeks, PJ is very nice to deal with. The drawback is the rather large junction block which can lead to odd fitting. Requires creative fitting solutions at times. Not inexpensive.
Spiegler: Outstanding lines, very good fit, small junction block, not inexpensive
The lines I liked the very best were the custom made I ones I had done in LA about 25 years ago. The dude measured, cut, picked the best fittings and installed them for me. I think the cost was all of $55.00. I've not found any other place that makes them on the spot like that.
