This factory Mercedes tool I can get for $35:
http://startekinfo.de/etools/content/tool.jsp?toolno=900 589 27 43 00 or this one on Ebay for $48: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=380291209593&ssPageName=STRK:MEWAX:IT

The Ebay tool looks like it would work better in tight spaces with it's long reach but is probably a Made In China piece that may not last long. The Mercedes tool looks like someone made out of scrap parts and a ViceGrip. Anyone tried either of these?
