Like you, I have also asked the same question. People advise that Sigma 500DG Super is better than 420EX. About the price, 420EX is $1500 and Sigma is $1600. I am still considering which one to buy. Probably Sigma.

二手420ex都係一仟蚊樓下，又對應哂七個對焦點測光，加上350D已經有最常用的後簾同步同閃光燈補償功能，420ex又配合埋ETTL-II，一般用途都已經夠用，將來有錢又可以買埋580ex玩無線飛燈，一於買佢啦！

Sigma 果支都support wireless, 不過, 聽人講佢支燈的色溫同canon原廠果支有d唔同.

以下是sigma支燈的compatability list

The following comparison between 550EX and Sigma 500 DG Super is informative.
