The SX-SJB 5-string I ordered came on Monday... after looking it over I found very few flaws. There's just a bit of a lacquer run on the corner by the B-string, and the tuning ears have slight imperfections/scratches on them - because they're cheap! - but they work fine. Overall though the bass looks great, and very impressive for $100. I tightened the truss rod, put some guitar honey on the fretboard as it was a bit dried out, and lowered the action - intonation is close enough for now until I put new strings on, but for now the original strings aren't bad at all.
I took it to my weekly Monday night blues gig and played it for the majority of the night, then switched over to my custom. It's probably close to ten pounds, but balanced well. I'm used to using a comfort strap, but the weight wasn't obvious until I put on my custom, which weighs 8.5 lbs. Tone was surprisingly good, and the more I play it, the better I'm able to get different tones from it. the string spacing is narrow, as well as the neck, but I have medium sized hands, and it was very comfortable to play. I've got to say I like this bass better than the MIM jazz I bought - and sold - back in 2005. No real dead spots on the neck, and because of the spacing, is quite easy for me to play. All-in-all it's a good purchase, and doesn't need any immediate upgrades other than a set of new strings. I bought a set of Indie flatwounds along with the bass, and will put them on soon to see how they sound.
The only other thing I will need to address soon is sanding the nut down, as it's a bit too high, and will be replaced eventually with a better nut material... any suggestions on what to use?
Makes me think of buying a fretless now....
