I've seen things people have bough or made for supporting your machine to remove the legs. I was in a big box store the other day and saw a Roller Stand and though I could modify it easily enough to support a pin. The Roller Stands was about $20 and I had some iron angle already, so it didn't cost too much and is nice and portable.
Here are some pics of my little project for those interested...

Cut off the roller part and cut angle to match width:

I cut the neck so that it would be parallel to the ground (25 degrees I think it was). Note, that you have to also bent the "roller base" out a bit to match the new angle:

I used some 2-part epoxy to combine the "roller base" and the angle iron. Then sprayed it some liquid rubber to coat it:

Folds up nice and compact..
