Currently I use Circle, but what about you?

Hey all,

In searching through various ways to turn my native currency into Bitcoin I stumbled upon Circle. I found it easy to use and fast, though the exchange rate can sometimes be up to $10 above market value (Bitstamp).

My question to you...

What do you use to transfer centralized currency into crypto? Does anyone think circle is untrustworthy?

Thanks for any response!
