Got one 
Placed an order over the weekend here http://www.lambda-tek.com/componentshop/index.pl?origin=gbase26.9&prodID=B239028 after seeing a post on another site which confirmed receipt of an ‘A’ model.
The drive arrived today and the Model is an IHAS424-32 A manufactured in December 2009.
I have also read that people have received different faceplates depending on model and mine (from left to right) is completely full with the following logos:-
LITEON, Smarterase, DVD Multi Recorder, Lightscribe, RW DVD+R DL & Compact Disc Rewritable Ultra Speed. This actually differs from the picture on the companies website and strangely enough the picture on the recorder’s box.
The following link shows a picture of what the drive looks like http://www.eworldsale.com/images/products/computer/cd_dvd/AA75678a.jpg
The only thing I would say about trying to find one of these is that most if not all companies appear to not know of the distinction between the A & Y versions and, even if you ask them to let you know which they stock, they probably won’t tell you. With regard to the company I used I actually just took a risk and ordered the drive based on the the post I mentioned earlier.
Hope this help anyone looking for the A model.
