Great question. It is definitely not in your best interest to search for homes with different Realtors. You should definitely hire a buyer agent and they will represent just your interests.
I am extremely passionate about consumers knowing their rights and every buyer has the right to representation and should definitely take advantage of it. By searching with different Realtors you are actually then considered a customer and not a client. You should want to be a client.
If you are not familiar with buyer agency, you should definitely do your homework. I have heard so many horror stories from buyers who didn't know who was representing them or because their Realtor was a dual agent and it winded up costing them a lot of money.
You should interview a few Realtors to see which one best suits your needs.
Feel free to read my blog, I write a lot about buyer agency. You may find it helpful. http://www.reneeporsia.com
Good luck and know your rights.
