Solid aluminum one is here: http://www.etoolcart.com/volvo-Oil-F...V9995679D.aspx for about $40.
I have the IPD one: http://www.ipdusa.com/products/5022/...ket-heavy-duty which now goes for about $40...though I bought it for about $25 a few years back...
Both will work...straps, big channel locks, etc. not recommended as you can damage the housing and it's $25 or so...that's money better spent on the wrench.
IPD sells a cheaper one for about $11, but I haven't used it, so I can't vouch for it...
