By Starcaster do you mean the "Strat pack" starting kit with a guitar, 10watt amp and lead?
If so, I believe this is the best possible choice for anybody learning to play the electric guitar. Quality instrument, the amp is crap (if its still the squier 10w) but it is more than good enough to set you on your way.
Stratocasters have 3 single coil pickups, when you use high gain (the distorted rock sound) it will tend to be a little noisier (buzzzzzzzzz sound) than a guitar with a humbucker pickup (looks like 2 singlecoils stuck together), the single coil pickups tend to have a brighter and more vibrant tone, where as a humbucker (less buzzz) is usually a little more high output with more upper mids and will sound more focussed.
Either way, it is a great starting guitar, but the amp that comes with the "Starcaster" set isnt so great. You may be better looking at a standalone Fender Stratocaster guitar, and getting an amp from say Peavey, Marshall or Line 6 (popular and quality amps in the low cost range).
If you mean the Fender Starcaster acoustic guitar set, well it is cheap as chips. It will do the job but don't expect magic, it is much easier to make a quality and great sounding electric for cheap than it is to make an acoustic (in my opinion).
