jerseys, shorts - $30-40 max
gloves - $20 max
helmet - $30 max
shoes - $60-80 max, although the first pair I bought was over $120 - it was in Australia where the markup is higher
socks - $5/pair max
sunglasses - $40-50 max

I have one pair of Performance bibs, it was around $40. I rarely use them as I'm not sold on bibs.

I think a lot of cycling clothing is horrifically overpriced without adding much value. I'd rather spend my money on beer, travel, concerts, etc.
