I was reading in another thread about some people who purchased repros through Charlie at gamecab.com and I'm trying to understand what the current options are. From what I understand, they are the following:
1) Buy used original yoke on ebay
2) Gamecab (

- can you still order through them?)
3) Apache controls (I believe they said it was "under consideration")
4) Ram controls (~$200, ETA unknown)
Personally, I'm getting a bit excited about the Ram Controls option. I've corresponded with David @ Ram Controls a few times, and he seems to be a great guy with a real passion for this. Hopefully that will translate to a great repro.
Any other options? Oh, there's also Menace's "build your own". Forgot about that.
