Test kits --Lovely Reader Meter Made

There are several companies that market general purpose "field" spectrophotometers and colorimeters.

LaMotte has a "SMART Spectro" for around $1,600 plus another $350 for essential extras and a "SMART Colorimeter" for $900 plus another $285 for the extras.  Both use LaMotte reagent kits that cost from $13.50 (high range Phosphate) to  $146 (Ozone) with around $30 for the mean.

Both sets, of course, have far greater precision and accuracy that even the most fanatical of us could possibly need.  However, If I won the lottery......

I wonder if there would be a market for a much cheaper colorimeter if the trade offs in precision, accuracy, etc were acceptable?
