I use Ektachrome 22 paper as my standard, and to date find only the Cibachrome
glossy paper to be any better in contrast, sharpness, or color saturation.

I use the paper with the Besseler 3-step and Ciba drums and get marvelous
results. First, I found that I can get away with using only 6-8 oz. of
pre-soak and rinse water (at 120F). This allows use of the Ciba drum which
has a smallish chemical cup. Second, I found that if I fill a LARGE
(>1/2 Gal.) container with water at about 122 F and fill my graduate from
there 10-20 sec. before the rinse cycle it works out just right. By the
way, if your water temp is off by 1-2 degrees don't sweat it since the 
purpose of the rinse is to keep the paper/drum temp up to prevent cool-down
of the chemistry when it's introduced into the drum. The ambient differences
in room temp from day to day makes just as much difference (i.e., negligible).

E22 certainly is one of the most economical ways to go for color printing
and can even be exposed for short (<3 sec) periods to a Jobo Minilux
safelight!
