Using a real estate agent was a huge mistake every time I've ever done it. When I went through the process on my own, it was WAY smoother and WAY less costly. Regardless of the bullshit anyone tries to feed you, you and the seller are both paying for the agents.
I actually bought my first home without one and everything went great. I have no idea why I decided to use one on subsequent transactions, but I'm back to not being a dumbass. They literally add no value if you can think your way out of a wet paper bag. I guess I should also consider that some people are rather stupid and may need help from someone who is only marginally less worthless, but the fact that you're asking for advice up front means you're probably smart.
Also, SandEagle is right - don't use recommendations from an agent or a broker unless you independently arrive at the same decision through research or a recommendation from a person who doesn't have a hand in your pocket. Kickbacks for recommendations are both extremely common and directly in opposition with your best interests.
The best piece of advice I can give you is to relax and realize it's just a house. You've been fine so far without it and you'll continue to be fine if you don't get the one you think you really want. People get caught up in the whole ordeal and think they're missing out on a dream if a particular house doesn't end up in their possession. Don't let anyone pressure you into buying a house if you aren't 100.000% sure it's exactly what you want in the location you want at the pricepoint you want at the terms you want.
This is the single biggest thing I didn't understand until multiple transactions. YOU are in the driver's seat, but everyone throughout the whole process will be trying to drive from the backseat. If you don't like something, put your fucking foot down and make sure people know they aren't going to get their way. I'm being slightly abrasive about this for a reason; experience has led me to understand how the whole system really works. Almost no one involved has your best interests in mind, but they're all masterfully trained to make you think they really care and their number one priority is you. It's absolutely the opposite.
