I've been watching a few videos while drooling over my options but have come across a question I can't quite figure out. I'm under the impression that the SF has 2 generations, one with detachable doors and one without. Which is the current version?

Not that it makes any difference right now. I'm hoping to have saved enough money by my birthday.

I'd consider making my own stuff, but then I remember the horrible sewing machine incident of 1995...
