Digital BW, The Print

I've seen a couple threads advocating either using Canon's software to convert to TIFFs or some kind of DNG converter. I only have PSCS and have been happy as a clam with it. If I want to use PS RAW must I really upgrade?

Looks like I'm really getting one of these babies. And an Epson 7900!! It's like Christmas over here at my house. There's a place in the Chicago 'burbs that I am ordering the 7900 from, and they couldn't be nicer. I figure paying the hefty sales tax is worth having help and service close by. Going out there to check it out and do a couple of test prints.

 I know the learning curve is going to be a little steep for me (see previous thread about MIS carts!) but my business is taking off and I need to learn. Verrrry excited. I will NOT junk my r1800, though, even though I have a serious problem with it's crap feed mechanism, I still love the way 3MK looks.

So....do all you 5D II owners use CS4?

thanks!
