Mellotronists

Hi,

I just want to sound like Woolly Wolstenholme (Barclay James Harvest )
without actually having to buy an M300. 

I've got the M-Tron but it doesn't sound remotely like, either M300
strings or M300 violins ( the only M-Tron voices I like are the cello,
saxophone, boys choir and clarinet, generally it's quite disappointing).  

As I understand it Woolly  never changed banks on his M300,
I assume he could only mix one other sound with strings which I
believe were M300a.

I could be persuaded to buy the Mellotron CD and a software sampler.
Could that provide something close? I only play for my own amusement
and to inflict pain on others, so near enough would do.

I've looked at the Kontackt and Vsampler, how much memory do these
things need to perform?

Thanks

Mark

PS These days with Maestoso he has an M400 with remastered strings but
they don't sound as good.

PPS I am not trying to restart the samples vs real thing debate!
