It took me a fair few years before I ordered my Sei bass [url="http://www.seibass.com"]www.seibass.com[/url]
'Jezebel' (as my wife called it) sits pride of place in my rack. for a 7 string, the Sei is surprisingly light and that, combined with the neck profile, makes it a great bass to play. It sounds pretty good too.
The newest addition is the James Tyler bass I bought a couple of weeks ago. I've played a lot of 4 string basses, but the Tyler takes some beating. It's incredibly light (it could be made of Mamywo - waiting for Tyler to confirm this), but the neck shape is unbelivably comfortable. It has an 18v Demeter preamp with switchable mids which I'm still trying to decipher.
I'm looking forward to getting an ACG 9 string later this year. The facings of mahogany are going to be teamed with an acrylicised spalted maple 'board. It's going to be an amazing instrument both in looks and sound.
