Gaming DSi Housing Replacements

[Exotica]

Hey, I was planning to replace my DSi's home shell and was wondering if anyone can recommend me a case.
All I'm really looking for is good feedback from anyone who's replaced theirs, like:
If it fits nicely (not too loose or creaky)
Responsive Buttons
And if it feels like a toy from a Chinese dollar store.
Anything around 20$ is fine, and color/design is pretty irrelevant.
Semi-related, I replaced my PSP's case a little while ago (with the help of the excellent guide here) and it feels alright. Buttons are a bit stiff, but at least they don't get stuck anymore.

Thanks in advance everyone.

I got one from DealExtreme but its cracking and it feels really cheap.
Ascetically it looks awesome (clear) but it was a hair to small and the pieces done fit perfectly

I second this - I got my DS (not-i) housing from dealextreme for about $17 - it is great, no crackings or like. So the quality really differs.
But prior to ordering I have read every single comment and review on all availalable items.
