Yes, that is a commonality that should be expected. Most companies all of sorts are weary about sending parts to a customer, and prefer to only send them to repair shops. This is for two main reasons:
1.) Most users have no idea what they're doing, which may very well result in breaking the parts they order... A company does not want to deal with this crap.
2.) For liability reasons you cannot advocate the user, of a purchased electronic device, opening and attempting to repair it... If you lack understanding, you can easily hurt yourself (try getting shocked by the ballast's initial lamp voltage spike...).
"because of a $3 piece of glass with $4 worth of electronics"
A color wheel may look simple, but it is a great feat of engineering. A single set filter 4x color wheel spins 240 times a second! While being timed exactly with the refreshes of each dmd pixel. That requires an insane amount of precision and balance. The glass most withstand the heat from a high pressure mercury vapor lamp. Couple this with high tech color filters that let through the allowed light and reflect the rest of the spectrum, as opposed to absorbing the disallowed light and heating up (what most cheap filters do), and you'll see why color wheels are expensive.
