I do not light those cameras at all, although, they are priced really good!
The NX100 is what I'd probably be after (though I might consider a bigger investment in an NX200 when it arrives, if it's a big enough improvement). The drawback is obvious; poor high ISO noise levels. But there are a bunch of positives; two (i.e. better than a Rebel) control dials/wheels in very Canonesque locations, plus a third if you're using an i-Function lens; an excellent LCD that is very suited to a Clearviewer; much better lens lineup than Sony's, including one decent pancake (20mm) and one excellent pancake (30mm) that appears to beat even the Panny 20/1.7. Not to mention that after some eBay wheeling and dealing the, NX100 body can probably be had for around $175!
Of course, I'd probably get pretty dissatisfied pretty quickly, and wind up plunking the money on an X100 mark II...
