Can't go wrong with $185 shipped. I would highly recommend you know *something* about electronics before tackling a project like this though. Double check the resistors with a meter before you solder them in - I had one mislabled as a 100 ohm when it was a 100k (or vise versa, I forget). The bands on those 1% resistors are almost impossible to read... (Is that red or brown?

)
Overall, I'm very satisfied with it. It's got a nice fast response time, and seems to be pretty accurate.
