I've owned one for the last 16 years. It's a good bass in my opinion and I like the style of the flame bridge, and the flames on the fretboard.
The styling is not for everybody. However, they make more than just the Phoenix bass with the flames bridge.
Do you know which models you saw for sale?
They are not an expensive or boutique bass. I've heard that the earlier versions were better made (Korea? I'm not sure), but then production
was moved to somewhere else (Indonesia? again, a guess. My memory isn't what it used to be), and quality dropped off.
They made some that were upgraded with EMG pickups. To be honest, I wish I had spent the extra money and gotten that model, although I
can always drop a pair in myself.
The construction of my Phoenix is excellent, no issues with frets poking out, the neck, body, tuners, bridge are all still solid after all this time.
I just don't like the tone I get out of the active preamp and pickups, which is why I would like to try it with the EMG's.
The price you listed is just about what they went for new in USD without the EMG pickups. If I remember correctly, I got my Phoenix 4 string
with stock pickups in 2006 for somewhere around $550.
