Mid-2010 Mac Mini, dead optical drive: Are any slim Firewire DVD burners compatible?

Question

The optical drive on my Mac Mini seems to have died prematurely, as the OEM drives are known to do. Estimated cost of replacing the internal component: $170. And it would be the exact same model Apple optical drive, not a more robust one.
Now very reluctantly thinking of adding yet another peripheral. USB ports are pretty well filled but I don't use the Firewire port for anything.
Trouble is, since Apple discontinued Firewire, the manufacturers of Mac-compatible optical drives aren't making Firewire models any more.
There are a few recent Firewire DVD burners from PC peripheral manufacturers, such as Acer, Aopen, Dell, Pioneer, Sony (Amazon reviews say it's restricted to burning Sony media) in a small "slim" form factor.
Anyone have information about their compatibility with Firewire 800 on mid-2010 Mac mini, Mac OS 10.10.1 Yosemite?

There are some steps involved which may translate to tedium,
as noted in the repair guide for the Mid 2010 Mini from iFixit.

At about Step 25, of an overall rated Difficult process, you can
see the Optical Drive, and likely be at a point to install replace-
ment, then reverse the process; paying heed to advice given.

At least you can get into this computer. Be sure to have a spare
optical drive cable and other possible items that may get broken
in the process. Oh there also is a PRAM battery in this computer
that may or may not need replacement while it is open...
If at one point, if several parts were to be replaced at one time, a
visit to a service technician becomes very cost effective. Find one
that will install the parts you may get from third-party sources. If
you know someone at a college computer lab, they may be able
to perform the swap, test their work, and be done, in short order.
Or, chose to use an external inexpensive 'superdrive' equivalent.
I'd heard the LG brand was among some that work, and can also
be used to boot the computer from System DVD or utility discs...
It is a USB drive, can burn DVD/CD media, and is not costly.
The ability to swap out the defective optical drive, and replace it
with an SSD or second storage drive, may be a way to go; but
it also would be at least as tedious as optical drive replacement.
This may add value to the device, in a resale situation later.
That would use the 'drive doubler' idea referred to at macsales.
In the above main guide, is a primer on how to swap out the optical
drive and replace it with a second hard disk drive or solid state drive.
Similar to what the OWC site says, but they have a good kit, too.
Good luck & happy computing!
