If you're going to spend money, I'd spend more on shorts than jerseys.

For jerseys, I've bought a few from Performance Bike, I have a sleeveless and a short sleeve jersey in their Divine model. Not fantastic, but they are wicking (a good thing!). I like having pockets to hold my inhaler when I dont' have my bento box on my bike. If you need to have something handy (gels, medication, etc), the pockets can be a lifesaver.

My shorts, I'm more picky, but I ride ~100 miles a week. I love my Sugoi evolution shorty shorts. They cost ~$90 retail, but they are worth every penny in my opinion. Not having a sore rear is important in my book
