I use both Tetenal film (process C-41) and paper (RA-4) chemistry in my
Darkroom. I am very satisfied with the results so go ahead and use it.

I use Tetenal frequently. Ultrafin Plus is perfect for Delta 400 and
Eukobrom gives excelent results with Ilford Multigrade Express and DeLuxe
papers.

I "was" a Tetenal user -- but found a place nearby (Unique Photo) which
carries the Kodak C41 and RA4 chemistry in gallon and 5 gallon quantities --
and the price was lower.  Tetenal quality is very good, I switched for
"cheaper" -- going from litre to gallon.

Haven't used their B&W chem yet, but their E6, C41, and RA are quite
good. If you decide to get it, don't miss their "first-time chem user"
discount. Something like 50%. Go to their web www.jobo-usa.com ->
analog -> product -> blah-blah -> "first-time user discount program".

They have two E6: one 3-bath type, one 6-bath-type. I've used both,
didn't noticed the result difference, but decided to stay with the
6-bath. Simply because it's more "conventional". I've read from the new
group that the 3-bath may be less desirable for Fuji's Velvia, but it
seemde never get second, and Jobo denied it. A good thing about the
Tentenal E6 is, it's reusable, unlike Kodak's current E6 that is for
one-shot only. You probably get more roll per gallon from Tentenal.

They have 3 or more types of RA, I've used the 10-litter package type
for my desktop roller processor. It's very economical, replentish rate
is about 10-cc per 8x10 print. Compared to Kodak's RA, I found it
produced less contrast prints, that helped to keep details in both the
dark and the highlight. However, The college that I took the color
photography class prefered the Kodak for the same reason.

Their C41 is also very good. I didn't notice its the difference
compared to Kodak. I used it mainly because it has more convenient
package. If I remember it right, they had liquid packages for mixing to
1-lit, 2.5-lit, and 1-gal (or 5-lit?). They also has the powdered
package for mixing to 1-lit. Very convenient for traveling.
