www.vetcosurplus.com Vetco - Bellevue electronics and supplies shop (This longtime favorite can be a bit hard to find. It’s on the north side of Northrup Way, a bit east of 124th Ave. NE. And once you arrive, the place can be a bit bewildering. Plan on spending some time browsing to understand what’s there and be aware that the stock is constantly changing.)
