What DVD-Drive Does The New Arcade Have?

[Sisee]

The title kind of explains itself.

I know of the ways to tell when you're holding a machine, but I want to find out before I buy it, if possible.

I managed to make a complete mess of trying to flash my Elite, and I'm looking for a console to replace it.
But I could do with knowing what DVD Drive is in the latest Arcade models before I buy one, as I'm thinking of taking out the drive and sending it off for an expert in such matters to flash it, rather than risking it again myself. Then I was planning on taking all the insides from the Arcade machine and putting my Elites case on it. Essentially it'll be a Arcade, just in a black case.
I'm sure most of the drives now can be done, but I'd still like to make an informed decision before I buy one.
I don't want to buy a new Arcade machine and find out the fellow I choose to flash it can't do it.

All drives can be flashed now and would most likely be a liteon drive, you would either need a kit or some soldering to obtain they key off the drive on a liteon
