The Wellgo's get lousy reviews. That is not well spent money:

You should be able to find some new M520s (demand the cleats or you'll spend an extra $10) on Craigslist that someone took off their new bike for some more expensive pedals. They work.

I bought some Forte Carve pedals at Performance for $35 about a year ago. They fluctuate in price, but are that price in the latest print catalog. They are light at 295g and I've had no troubles with them whatsoever. Any issues with stuff bought at Performance are returnable at anytime. SPD compatible.
