Smallest, lightest, most portable - quality mixer?

[Dirty Beats]

I'm going down to Costa Rica for a Bachelor party and I'm told the house has a decent stereo.
I'm thinking, since I comfortably and easily DJ off my laptop using final scratch in INT mode, I can just bring my laptop, a Serato box and all I'm missing is a mixer.

I was thinking about picking up one of these for $100 but thought I'd come here and see if anyone else had a better suggestion.

(Figured I could get a RCA -> 3.5 adapter for the input.)

Does anyone have a better recommendation? I want it to be really light and portable.

Basically, I need two stereo inputs, preferably RCA.
two channel mixer... Doesn't even need a cross fader.. Just up/down faders.. But with trim, low, high and mid if available.. Cue for each channel and a master.
RCA output...

Thanks.

Or is there a really light, portable, small CONTROLLER that would work well for this application?
MUST BE:
Scratch Live compatible.

small in size but not really quality quality.

i'd say this is the quality i'd start with, in your situation at least.

this is compatible with itch at least. Traktor too.

An M-Audio X-Session is pretty small, has some controller functions, does not require drivers, and connects with a single USB cable. It's good quality and reasonably priced. I'm very happy with mine.
