Measuring 0805 Capacitor values under 1nF
You could buy one of those cheap Chinese LCR meters. About $6-10 including shipping and they'll measure down to 30pF or so. 

Here's a 47pF 50V 0805 capacitor measured with hand-held jumper leads: 



I would check it with my LCR bridge if it was important but you can't beat the price/performance of these things. The design has evolved from a US published front end and hobbyist copy using an AVR and the published equations.
