You asked the wrong folks

I am going from memory so my years may be off. Starfire basses were first produced circa 1964 to 1977. The traditional start date is 1965 but there are documented sightings in 1964. Fender did a reissue in the late 1990's - I'd say 1997-1999. The DeArmond by Guild Starfire is also considered an acceptable substitute and dates to late '90's/early 00's.
I'd say at any given moment I could find 3 to 5 vintage Starfire basses for sale. The reason they might appear scarce is that most people think scarce really means "priced for more than I could or would ever afford". Prices are dropping from the record $3,500 for a SF I down to a more recent $1,600 for a Starfire I in reasonable condition. But right now there are several sitting at dealers with prices north of $2,000.
No one has ever discussed the sound difference between the maple and mahogany. Usually it is the color. The real sound driver is the pickup. The earliest ones had at least one variation, the "Mickey Mouse" PU. From some time in 1965 through some time in 1970 they used a Hagstrom Bisonic which is the Holy Grail. From 1971 through 1977 they had a Guild humbucker which is an acquired taste. Most folks who have heard a Hagstrom either insist on one or plan on replacing the PUs with
Dark Stars.
Finishes I know of are natural, burst, cherry, green, brown and black. In the wrong light or in some photographs it is difficult to tell the green from the black. What I called natural may actually include several different finishes.
I don't know that they are especially difficult to work on. Parts will be a problem if you want vintage. The saddles often split and
this source gets about $60 for a set. The guy who makes them sometimes posts here. See
PeteyBass here for a discussion of metal saddles. Vintage bridges and knobs are pretty rare and command fairly steep prices ($100+ for a bridge, $25+ per knob and more if there is a complete set). If vintage is important to you then I would not even consider anything unless all the parts were there, original and working.
I've never played a reissue or a DeArmond. Generally the vintage with Bisonic will command more than the vintage with humbuckers which gets only slightly more than the reissue which commands more than the DeArmond.
I have only personally played a vintage with Bisonic, but I have the humbuckers in my JS and have been told by people I believe that they don't sound that much different in a Starfire. Now that you know the basic variations there are sound clips on YouTube. There is a DeArmond for sale
here.
I have been quite happy with my SF I and folks with SF II's have reported using only the neck PU for as much as 85% of their playing so the choice between a SF I and II may hinge more on availability than utility.
I'm tired of typing but you get the idea :wink:
