One thing we don't have as our old Tektronics one died is a SPG. Looking at something a bit future proof and I happened upon the Dcode Sb-T from Denecke. This quite little box claims to generate everything a man could need and will run off batteries. No clue as to the cost yet, just wondering if anyone knows of anything else they'd care to recommend.

Another little useful gadget I came upon, a Target Chart that you can set for ANYTHING, probably of more use to the 35mm guys (one designed it) but still if you shoot video and need to keep everything within an odd AR this would be a big help:

It's towards the bottom of the page.
