You can buy Shimano, double sided, pedals for less than $50, and have the best of both worlds. Either the PDM324 , or A530 are my choices, and I have both.
Shimano A530 Sport/Touring Road Pedals
You can also buy Shimano MTB shoes for around $50.
Soooo, if you are interested, start watching the sales, and get in for less than $100.
No kidding!
