A review on flashes in this months photoplus mag. While the 430exII came out as best on test the Sigma EF-530DG super came out as best buy. The cheapest was a Jessops number - 360 AFD and it scored 70% on test, compared to 95% for the 430exII.
The jessops flash
+ was Good all round manual controls and wide angle diffuser.
- was slow recycling time (7 secs) and not compatible with 50D
