As opposed to my (already discussed) preference for cheap sunglasses, I don't believe in cheap jerseys. I buy the good stuff, to me it's easily worth the extra money with the better fit, better construction, better fabrics, better look etc. Ornot and MAAP make my favorite summer jerseys at reasonable prices.
One tip: wash all cycling stuff in mesh laundry bags away from anything velcro and hang dry. If you do that, cycling stuff will easily last years.
