Multiple Small Supplier Vendor Master ??

  We are on version 8.0
 
  We have the need to make small purchases of inventory for one-time use on 
custom-modified product, from suplliers not used in the normal standard 
production. We don't want to go through the process of establishing a suplier 
record for a single use - and have a supplier record for a company that hasn't 
been approved for general use. 
 
  We have been using a credit card purchasing routine, but this leads to 
non-standard, forgotten procedures for receiving, etc.
 
   Has anyone used a "Miscellaneous Purchases" vendor for this purpose - so 
that a PO will exist that we can receive against?  Is there a better way?
 
   Thanks for you ideas.
