Flash for Canon XT

[mandarins]

Looking to purchase a flash for my Canon EOS Rebel XT.

Use: night time, street, fill, etc.

Looking for good quality.

Thoughts on
Canon 580EX
Canon 430EX
Canon 220 EX

Others?

What are your experiences with these?

Some degree of manual control is a must.

Thanks!
