Wow - thanks for all the feedback!
@Dad3353 - Yes, you can call me Ben. It is my name after all
Loads of really useful stuff.
Having re-read my first post it was a bit wooly. I do plan to have lessons - thank you for the recommendations, and I know I need something to practice on!
I guess the questions come down to:
a) Do I save up a bit and get a reasonable quality bass? Something that I'm not going to feel I want to trade up in a year or so.
If so I'm not 100% comfortable that with my current skill level I'd be in a place to make an informed choice - i.e. if I want a p or a j neck, pup types etc so would it be worth having a couple of lessons where I can use a few different basses to have a better idea of what I like playing?
I'm also conscious that a better bass should be nicer to learn on, though I haven't played a new bass in years so the quality gap may be much smaller.
or
b} just buy a cheap bass to start and plan of changing it when I have more experience?
Option b can happen sooner, but if I get something much nicer by waiting a few months then I'm happy to do that.
Having looked online I like the look/idea of these basses - but obviously have no idea how they play!

A few different styles off basses there, but I guess they are all pretty classic/vintage styles.
If I went for option b I guess I'd be looking at something like the Jazz bass Darren linked to above: http://www.dv247.com/guitars/jandd-jb-vintage-1975-sfgr-bass-guitar-surf-green--201561
and I like the look of http://www.thomann.de/gb/harley_benton_pb_50_sb_vintage_series.htm but that seems stupid cheap to expect a reasonable bass.
or I'll need to look 2nd hand.
I appear to be incapable of writing short, concise posts today! Thanks for bearing with all my waffle!
