Okay all you seasoned professional inspectors out there.... what's the skinny on the best hardware out there for home inspectors?

Digital Cameras
Electronic data gathering

What do you all use/recommend/wish you had !? Kind of have my eye on some things, but due to sheer numbers of different products available, I just as soon hear from you guys/gals in the field. What has been field tested and to your liking?

Thanks in advance for any and all tips and suggestions.
