Paul - sf 3.3 is still expensive, you may be better trying to get the US version as it is usually about $50 - $75 cheaper than the japanese version
I have a complete SF3.3 Japanese Version A and I've been offered (and turned down) over $500 US for mine.
side note - expect to see some dead SF3.3's poping up this year, unless of course the batterys have been swapped
