Know it's tiresome but you should try to get a handheld meter for incident and flash. The in-camera meter approach only really works if you know how to use a spot meter. Using it for centre-weighted reflected readings can be hit or miss and still assume some savvy at reading backlighting or bright areas in a scene. Incident isn't fooled as easily and delivers more consistency--the grail, right? With some snooping around, you should be able to get an incident meter--and possibly a incident/reflected/flash model--for your budget. They make life easier and help save face.
