Well i've only used Celga, if it ain't broke 
don't fix it. Personally I love them, they have 
brought me closer to so many wonderful items. I 
collect only Lain items, not just cels but also 
hard to acquire memorabilia. The items range in 
price since Lain items can be very mercurial, and 
very volatile if you get a bunch of Lain fanatics 
in the same room. Some can be very cheap, others 
eye popping @_@x. I'm limited in my use since the 
items can be quite rare and infrequent and not 
obtainable here, but I request their service when 
I can. I love the fact they take care in packing 
the items well regardless of price since the 
items mean more to me than the money I could 
save. All I can say is when it rains it pours. 
Here's a pic of celgas lastest effort for me, a 
lain dvd promo poster(nfs). They are great. ^_^x
