Heck I just add some scraped cells with a pipet tip to 5 ul H2O and pipet a 
few times to mix.  Then, add 20 ul of my PCR master mix, oil, and toss in the 
thermocycler (with a preheat of 5 min at 94C) and all goes smoothly.  No 
dilution, no extra steps, just remember to change your tips each time so 
there's no carry-over.
