I personally have more luck with the surveys. They tend to pay more all at once, and the researchers aren't as shady as some of the transcription requesters. Surveys have potential for follow ups and bonuses too - I just finished a series of surveys about where I've seen advertisements for new movies that paid .50 for 2 minutes. Did 13 of those over 14 days, and got a $5 bonus today for finishing enough of them. Easy peasy work for almost $12!
It all depends on what you find that you enjoy doing though!
I recommend using Firefox or Chrome and downloading some scripts.
Hit Scrapper has increased my earnings so much since I started turking with it. It basically lists all the current hits based on your criteria, along with showing the rating for the requestors, so you have one list of hits to do. So much easier than trying to search the actual website for a hit to do.
There are also some places where other turkers post hits that are worth doing.

You might want to focus on building up your numbers until you're above 500/1000/etc, since that will unlock more hits for you. This is the link for a receipt hit where you just decide if two receipts are the same or not. They auto approve in 7 days, so you'll have to wait a bit, but they're super easy and great for number building.

Ben Peterson is another great and easy hit (rate a dating profile picture for 3 cents, approves quickly), so is Venue Quality. If you have a dual monitor you can knock out Jimmy Dragon business card hits quickly and I've never had a rejection from him.
Definitely a lot of potential with it once you understand it! I made $21 today for only 2 hours worth of surveys while DD was asleep.
