Get this:
or the full size version for 10 bucks more.
They also make a clip on - and those are super handy to have ( I use my clip ons WAY more than than my board-based tuners - they're just so much more convenient). But I would say just get a Snark Clip-On and keep one in each case or one in the car, etc.
The Boss TU2 is priced similarly and I agree with what others say - also a fine tuner (pun intended) and solid. The extra money from what you're looking at is justified either way - it'll last a REALLY long time ;-)
The cheap ones probably won't.
