I have a case of 'didn't buyer's remorse' today. 😔
£145 for (what I assume was) an SB405 in good working order - seems an absolute bargain.
Having said that, I've never owned a five string, so I don't know if I'd like that aspect. Plus, all my basses are passive, and active basses seem to be generally out of favour these day (with the exception of Stingrays). Finally, from these pages, I note that @Happy Jack prefers a P/J Nanyo over J/J, so perhaps the P/J configuration (on a Nanyo), sounds better...?
