Body Saw Recommendations

[special-K]

I've pretty well using my judgement when buying tools n the past. But, I need to pick up a body saw and before I do I thought I'd use this great source of info we have here for some recommendations. Air or electric, quality of a brand, one design better than another, blade off set or centered better, etc? I guess I'm leaning towards air. I already have two sawzalls (one cordless), so this will be for specialized use where a sawzall won't do. I'd like it to be small/less bulky to work on the tightest places
