I know that we've all done it - bought gear, fell in love with it but for some reason felt that we needed to move it on - only to kick ourselves when we sell it. (Add your own list.)
I did this recently with a G&L M2000 - replaced it with a G&L Jazz which I moved on shortly after, replaced with a SB2 which I love. I've just had the opportunity to get my hands on another M2000 - hope it doesn't turn out that it's a case of reminiscing.
