I haven't found anybody local as low as the Argen Price.
you never will, either. argen is one of the biggest players in the game, so they have to have among the lowest prices. everything else if its local or smaller than argen's 3 digit employee roster, will necessarily have higher prices.
accept that, and redefine your strategy. don't ask little players to give you argen prices when clearly they can't match it.
they don't offer expensive models because they need to turn a profit. they are expensive because they cannot produce for lower. most labs who have argen's scanners and dongles are already paying argen for the right to play the game, so argen is already making their cut.
