Thanks guys for all the advice thus far. I was heavily considering a VM squier, they seem to be popular, but the criticisms that Squier's get is always off putting. Being labelled as a 'beginners' bass sometimes makes me concerned about their longevity with redards to durability and versatility.
I do often wonder why they get such bad stick in some places i look, maybe because 1 of their models recieves bad press people hold it against the whole brand!!!
Thats interesting about the consistency of the MIA models, for their price range id hope that they are all consistently top quality :/. But yeah, if i settle on the MIM then i will definitely try before I buy, its ashame that Fender dont iron out this discrepancy with the MIM, £450+ is a huge chunk of money when you can't be sure of the quality.
I also considered the Ibanez ATK200 and another ibanez, the Roadster from the SR series, these are within my budget and look to be good basses.
I will certainly keep your advice in mind though and check out those VM's and Yamaha's, Cheers
