Ok. What compatible replacement laser assmebly do you reccomend?
Being it's in a tray loading Sega CD, does it have to be an EXACT
match? (will the Sega CD even know if the drive is changed?) Also,
what replacement will accept a CD-R, the best?

It has to be replaced with a KSS240A, and I would recommend a genuine Sony
one, if you can find a supplier. Do not use one of the subs such as the
NKS240A. I have never had much luck with them. If you find a website selling
lasers, you will often find two prices quoted. The cheaper one is usually
for a second-source replacement, and the slightly more expensive price is
for a genuine Sony original, which may be actually declared as such. I would
recommend going for the Sony original in the case of a KSS240, as they are
fussy lasers at the best of times. For products which use the KSS213B or
KSS213C, cheap second source replacements are usually fine. For KSS213D, E,
or F, again I tend to use genuine originals. If your unit is going to be
working a lot with home-burn discs, I would definitely go for a genuine Sony
replacement. No alignment should be necessary after replacement. As you say,
it shouldn't even 'know' that the laser has been replaced. There is not even
a shorting blob to remove on a '240. You can just drop the new one right in.
I would however recommend that you wear a wrist strap connected to an anti
static mat to do the job on, as laser diodes are quite sensitive to static
discharge, when their connections are open, as they are on the '240 until
it's plugged in.
