Digital BW, The Print

Hi, i'm newbie to this group. and in need of some advice:

i am a professional photographer and 90% of my business is wedding 
photography. Currently i send out all my digital files to lab to 
print my photos for my client albums.

i produce albums with 10x10 prints and i want to be able to produce 
all my prints at home. i have a cold laminator that i use to laminate 
all my photos in matte finish so archival issues and durability is 
not a problem with me.

I currently have a Canon i9100  with CFS from media street and love 
it for color but find it lacking for BW. I would like to print all my 
own prints for my clients and am looking for a system for BW to try 
out.

I am leaning towards a 1160 or 1280 with MIS ink over Piezo ink 
because of price. i would like to use a cartridge system and refill 
ink with MIS bottles. Is this possible? I know you can buy a chip 
resetter for ink refill carts. I heard the 1160 does not have a chip, 
is this correct?

Is the print quality and speed much better from the 1280 verse 1160?
btw, i am use to ripping out 13x19s from i9100 in three minutes or 
8x10s in about a minute.

In large areas of graduation, do you get banding from 1160 because of 
lower resolution?

Does any one have an 1280 or 1160 that they want to sell?


Thanks,

Scott
