I commute rather than pleasure ride... so I also go for hi-vis, low price. Which has resulted in me only owning one jersey, a plain neon yellow one I bought before I found
www.alertshirt.com. Technically alert shirts aren't jerseys but who cares they are bright enough to damage your retinas and they're $7.75 apiece

I'd like to try wool but I have no idea where you get decent blindingly obnoxious inexpensive wool shirts/jerseys.
