That is what has steered me clear of straights. The outlay of $$$ for everything required to do it right hasn't helped either. So I figure I kinda do have a straight already: the Rolls, the straight on a stick.
I know that I will wanna try it in the future. But for now it feels nice with the DE's and the SE's =D Why fix something thats not broken =P
I see that there are some free apps on Google to turn my phone into a magnifier/microscope and take pictures. Anyone tried those? I'll have to give those a try.
I just tried it and I think I'll go your route also. I'm keeping the app in my phone though; it could be useful for something else sometime.
The next step would be a fixture to secure the tool. If that fixture lets you adjust the height, you are all set.
