SVT15... maybe your friend lives in a very dry climate, as I've never heard of any "defects" in any CS basses.. even the less expensive "Team Built" production models. For this to have happened to two basses, leads me to think it's climate, and I've yet to see a bass (unless it's shrinkwrapped in poly finish) that doesn't react to moisture change.
Now, the bass above is a "Team Built" Custom Shop "Series production", i.e. not a "one of" or custom ordered instrument. BASE STREET PRICE of one is about $1890.. this one has a finish that carries a $150 premium, so that puts it at $2140 or so "Street" price, or about $3000 retail. Considering how hard to find these basses "IN STOCK" it is, the ebay auction is probably accurate. Keep in mind, just because every dealer shows a "CS Classic Jazz IV" on his site, doesn't actually means he has it, you'll have to wait 4-6 months.
As for comparing a CS to a Sadowsky, I would say they are comparable in quality (at least to the NYC), don't know much about skyline.. The Sadowsky NYC line has some very nice stuff for sure.
Keep in mind however, Fender's CS isn't the "King" it's their "Master Built" CS that takes that spot, and those start at about $6000 and go to $60,000+! before discounts
I've got a Dennis Galuszka "Master Built" on order now and it's loaded with a few customizations:
-2 piece light weight/tight grain Ash Body
-Ebony Fret board on 1/4 sawn (either AAA Flame, or Birds Eye) Maple neck
-Clear (barely viewable grain) Ebony or black NitroCellulose (for now) finish on the body
-Poly urethane on the neck headstock, and oil (matte) finished on the back of the neck.
-Natural abalone block inlay's and pick guard
-Initials "SJS" inside block inlay #7 to be made of a light color wood.
-ZERO Fret right in front of bone nut (you can see an example of this idea on Fender's website under the "Zero Fret Jazz Bass"
-9.75" custom radius neck
-1.5mm at 1st fret custom reduction on neck thickness at tapering to .5m at the 21st fret
-9v Dennis Galuszka custom designed pre-amp
-2 "Jaco" classic jazz, Dennis Galuszka hand wound J-pickups (over wound).
-Schaller light weight turning machines
-Roscoe Beck style 3-string string-tree (ADG coverage)
-Custom Shop G&G hand made "Tweed" case with red interior
And so far (at last check) it's at about $7000 retail and I'm getting some 33% off that! The price will change as you add and subtract stuff along the way, or change your mind, which I've done a 1/2 dozen times already.
