I'm not the one who pointed out Aiwa to you. I would have, because I own one. But msaeger beat me to it. Front panel AUX in was important to me last year when I was looking for a CD receiver.
I was quite happy with it. Although in the last year I have done a bit of learning about car and home audio and have decided I want a better one to take it's place. I've already picked out an Alpine I like, but it will be a little while before I can get it. Other things take precedence.
And as for RDS, I hadn't known it was so common "across the pond." So I imagine you're right about manufacturers usually incorporating it.
They are kinda cheap, but it's perfect for anyone who's just looking for a solid CD player without a lot of frills. That was me last year, and I got the model I mentioned for about $160, online, when it was new.
