Not sure which replacement optical drive to get

crwdns2934249:0crwdne2934249:0:

When I visit the parts page for my iMac model (iMac Intel 20" model A1174), the following statements appear:

[Works with] "All Intel iMacs with Panasonic drives (Early 2008 and older, excluding 24" iMac)"

And 

"This drive does not work in iMacs with Pioneer (DVR-K06RS) drives."

According to the "About this Mac" info, my iMac has a Pioneer drive model K05 (but not the Pioneer K06RS or a Panasonic drive). 

This makes me nervous. What is the right replacement optical drive for my iMac?
