Like:
Timbuk2 Bullitt pannier/messenger bag. Decent marriage of a pannier and messenger bag. Typical Timbuk2 quality (which is excellent).

Axiom Transit rack. Lighter and can handle more weight than my Topeak clip-on rack.

Sno-seal for the Brooks B17. Makes the saddle much more water-proof than Proofide.

Bontrager inner tube. Chrome plated stem and very well made overall. Best tubes I've seen thus far.

Continental Gatorskin Steel bead 28mm. Rolls easily and no flats for about 3 months of riding on very dirty (practically unused by peds.) sideways choked full of sharp pebbles, broken glass, etc...

REI OXT Airflyte Running Jacket with eVent Fabric. Super breathable and kept me dry from moisture within and without. Great as an windbreaker layer as well.

Tried:

Wald folding basket - the OEM mounting hardware sucks and doesn't suit my needs very well at all. The powdercoating rubbed off even after one week of usage.

Maglite AA LED flashlight (the newest kind with multi-mode). Great be-seen light with the strobe function but not bright enough for night use. I missed a dead animal by 1" on a dark and rainy night commute.

Backpack in hot weather. Rash developing on my back; sweaty, stinky mess by the time I finish my measly 2mi commute.
