I am in the final stages of implementation for www.bestamericanarts.com.  We have some drop-ship items that are "one of a kind", which netsuite doesn't really allow for.  If you choose "non-inventory item for resale", there is no way to control inventory amounts and therefore people could order as many of the items as they wanted without them ever going out of stock in netsuite.  For this reason, I have decided to simply add them as inventory items with a stock of 1 and made a new COGS account, sales account, etc. so that we can determine what we ACTUALLY have in inventory and what is entered as an inventory
