I've had a Stanley Sig Deluxe for about a year and a half. It's, of course, a great instrument, with a panoply of sounds (although I don't have an internal comparison of it versus a Series bass) ranging from booming to glassy to quacky to digital-sounding. Man, with the pickups set to 20% neck, dimed bridge, both q's flicked, and played with a plectrum, this thing zaps through walls of distorted guitars without difficulty.
Playability: the biggest thing for me to adjust to was squeezing my fingers between the frets above the level of about the fourteenth...if you've got big hands, you've really got to work on your dexterity and precision when handling this short scale thing. And, Dannobasso is very right: neck dive if you wear the strap high, but comfortable sitting down.
Overall, my Sig Deluxe is a beaut, and I'll be holding onto it for a while. Here's to your acquiring one.
