scalesgalore.com has a great selection and pricing for scales. That is where we purchased ours. Pricing varies so it all depends on how much you want to spend. Ohaus is top of the line. Using a Mettler Toldeo UPS shipping scale also. Bean urinals, that is what I refer to them. Great invention for getting the roasted beans in the bags for manual operation. About 30.00 each. I believe espressoparts.com has them. Moisture meter if you want quality, then go with a Shore Meter. 1,000.00 average. You can buy cheaper ones but you get what you pay for. Do you really need one is the question. Filtering system is important...the list can go on and on...figure the larger items such as a brewer/s, grinders, hot water brewer, espresso machine. As you well know there are many to choose from. We use Wilbur Curtis G4 brewers and Fetco. All Mahlkonig Grinders and a couple of Compak. Optipure filtering system OP350/16, Shore Moisture meter, bag sealer s from AIE and OK International. True Refrigeration, Ice-O-Matic ice machine, lots of tubing and push to connect connectors. Freezer is a plus. Ipad for your register. We just switched to Square from Shopkeep. Cash draw and if you need a receipt printer go with Star. A friend who is a electrician, plumber and HVAC is also a plus..just a drop in the hat!!!
