Yes, I picked a scale up for $12.00 and spent almost as much on the calibration weight required to keep it accurate. There were lots of scales to chose from all between $10.00 to $40.00 that were good enough for these small quantities.
Keep us all posted on your progress. By the way I caught the 3 gallon Carboys on a deal for free shipping. Shipping is a killer from some sites, running as much as $10 - $12.00 per carboy. 1 Gallon or 4 liter carboys are easy to come by at my local recycling center. I've gathered about 12 or more so far. (Lost count) Same for wine bottles, never buy them when I can get them free at the same place. Takes me no more than about 3-5 mins per bottle to clean off labels and get them ready for use.
