About 12 years ago I bought a couple of affordable 'stand alone' CD rom duplicators
which were ok for quickly running off batches of demo audio CDs
as and when required...

[shortly afterwards DVD/CD rom duplicators became available]

I don't know what equivalent product is on the market these days,
but might be worth investigating,
for any mudcatters who just want to burn the odd couple of dozen discs every now and then...???
