Krynos

I used to buy from them often until I decided to pay $300+ for a Pikachu N64. When it arrived, it was scratched to hell, beat up and absolutely filthy. I messaged them about it and they told me too bad, take it or leave it. For an extra $50 I could return it for a partial refund. I'll never buy anything of value from them ever again.

I use an LCD. There's no reason not to. I have a decent CRT for shooters though.
