I really want a NES. I never owned one back in the day, but I have been dying to get one now and I have some extra cash laying around. So my question should I go for a NES or a Retro Duo? I love the idea of a retro duo, but I think like the look of a NES more... Anyway does anyone know where I could buy a refurbished NES I don't really trust ebay, but I'm fine buying from any other website.

What is a retro duo?   
 
I don't know if could be bothered with an NES as the graphics are crap compared to the SNES  ^-^  It's all about the graphics.

The original NES is prone to fucking up and not connecting games properly,
Which requires a lot of fiddling with the cartridge.

 I really like this Retro Duo, I must have missed it.  I would go that and I would buy one if it was ever released in Australia. 
    

9 out of 10 doctors agree the Retro Duo should meet your needs quite nicely.

" @oldschool: I got mine on ebay, from a fellow as the Aussie seller no less. They appear every now and then down here. Mine's the evil-lookin' version, black with red detail. "

" Are you using a step down converter (or whatever it is) to power it?  Plus, what did it set you back?  Fortunately my SNES still works fine and I don't own any NES games, but I would pick some up if I could reliably play them. "

I never knew about the Retro Duo. I want and need one right now.

You could get a top loading NES.  They're pretty reliable. 

I got a Retro duo a little while back, and I have to admit it is pretty awesome. The only downside of it is that it comes with 3rd party controllers that are similar to the SNES ones. They just don't feel as responsive or solid though. A perfect solution though is to use an actual SNES controller. I was able to take one I had in the closet and use it with the retro duo. Works great. I do wish you could plug in an NES controller though

If you're playing for pure nostalgia, get the NES, if you just wanna play some NES and SNES games, get the duo, it's more reliable, as I have to regularly open the NES up and clean it. To the point where I've just kept the screws permanently removed. But it's also a little more satisfying, if you ask me.
