There's a reason I've been going to Rodi for at least 3 years. He's knowledgeable, friendly, honest, and he saves you money.
Two instances come to mind:
1) I told him I wanted a custom computer that had [insert computer jargon] to be able to do X, Y, Z. He said that the computer jargon I had in mind was "too powerful" for what my needs were. He recommended that I would be just as happy if I used [lesser-end computer jargon]. He was honest and trying to help me save money at the same time.
2) I went to him a different time and I told him I needed a laptop. I was skeptical at first because the price seemed too high (don't worry, it gets better). He told me to Google exactly what he recommended I buy from him. I accepted his challenge and Googled the exact laptop he was suggesting for me. It was nearly double the price to buy it online! The price "seemed high" because it was a higher-end laptop model. He was honest and saved me money again. (BTW, I still have, and use, that same laptop almost 3 years later)
Since these moments, I've stopped "questioning" him because I know he has what's best for me at heart. I appreciate that. And I know you will, too.
