Printing your own manga: Ka-Blam, Lulu or else?

Greetings everyone,

Since a lot of people here are manga artists, I was wondering if I could ask you something:



I've been visiting some PODs websites (Print On Demand) and so far, when it comes about publishing your own comic or manga, I've stumbled on KA-BLAM.com & LULU.com. I've read reviews from people who have used their services in the past and the opinions are quite mixed. I heard about ComiXpress, but it goes shot down...

Anyone among you ever experienced one of these printing services? And how was it? Who is better among these two? Please let me and everyone else hear about it. Thank you.
