Joe, I'm right there with you and will probably own one after this season just to play with before next year.
3 things are holding me back-
1. the amount of money I've already spent towards hunting this year
2. both of my bows are ready to roll
3. Rick James seems to be having issues with tuning this year[8D][&:](j/k brother, I did order that book you recommended) but I did notice broadheading tuning issues thus far and am waiting to see if he can get the bugs worked out while using the 360.
Being a containment restI can't help but think it will still be more critical to maintaining follow through during the shot.

IF after with playing with oneI loose no accuracy I could very well be shooting 2 by next season.
