I'm trying to find out if there's a way to form a Google query to quickly find out what position you are for a search term.
I know that Google Webmaster Tools and Google Analytics has something similar but I don't find it accurate.

If you want detailed reports on all the keywords and positions that you may not even be aware of your ranking for... then sadly your need to look at a paid service, you can get such reports using some of the following sites:following:
To check the difference between them you can take a look at Raven vs SeoProfiler vs SEOMoz, its worth noting that while these display keyword rankings they also offer many other solutions how to rank better, there may be a cheaper option than these without the other perks but I don't know of any so maybe someone else can help if your on a tight budget.
