Who can add a cartridge slot to an Atari Flashback 2?

[c0ldb33r]

I'm going to purchase an Atari Flashback 2+ this week.

Is it hard to add a cartidge slot? Is there any way to make it look nice and finished or does it look like raw plastic?

Has anyone done this? If so, can you post a few pictures?

Finally, assuming it looks decent, is there anyone I can pay to do this for me? :)

edit: neat-o, I found this pic online, the cart slot looks great there:

I had assumed that you'd have to stick it on the top of the unit. This particular one looks a little weird because it doesnt look like the cartridge goes in straight, it seems to go in at a slight angle. If they fixed that though, it'd be fantastic :)

edit 2: I found this pic of a cart slot on top - it looks pretty good, but it's not centered.

I also found this one (http://hackaday.com/2009/06/22/atari-2600-slim/), which is totally BADASS! It looks just like a real 2600 and has the cartridge on the top portion.

Can anyone do something like this?
