Where's the best place to buy a radio

[0utlander]

I've been working on my 1970 C10 Chevy for a few years now, and one of the first things I did was replace the old broken radio and speakers. Unfortunately, one year after making the switch the radio died on me. I'm still not sure if it was the radio or something else, but the fuse never blew so I have taken to blaming the cheap radio.

Well now I am looking to try again, and I was hoping someone on here could recommend a website or shop that sells good quality radios for my truck. I am hoping to keep the price of the radio and a couple speakers under 500, but maybe that isn't possible so just let me know if you have any ideas.

Thanks!
