Hi Glyndwr and welcome, That is my thread fatback has linked so I know where you are at. I cant recommend Gedo as a company enough, I dont know much about basses as such but the finish on mine is great, the company however are brilliant, well packed, free bag/case/bow and proper pops rosin. They returned my emails really quickly in english and did exactly as I asked (If you look on their website you will see they actually have mine listed as a model now with adjustable bridge and spirocore strings for 950 euros, tell them what you want if different from any on the site and they will list it as a special order for you to buy online, mine came within 5 days of ordering including fitting the bridge and setting it all up! I dont know what you have in mind as far as a budget is concerned but I would have no issue in buying one of their cheaper ones, this for example is 499 euros [url="http://www.gedo-musik.de/shop/product.php?id_product=703"]http://www.gedo-musik.de/shop/product.php?id_product=703[/url] and from what everyone else has said should be much better than G4M basses as far as the setup etc is concerned.
Also some nice basses for sale on this site from time to time but they get snapped up pretty quick which is another reason to get a reasonable one if you can as you could always get a fair chunk of the money back if you decide to sell it, a dirt cheap one will be good for nothing really.
Best of luck and it will be nice to have someone even newer to this than me
