Here's how I deal with the eyeliner issue: I tightline with a soft khol pencil (I use Rimmel). This means I apply liner very close to the lashline in a series of dots. It takes a little practice to get the technique down, but I find that it looks much better than my attempts to draw a line on my lids. Sometimes I tightline with an eyeliner brush and wet/dry eyeshadow. It looks really natural.
If you want a cheapie eye makeup base, then head on over to Ulta and pick up an eye shadow pencil from NYX (hypoallergenic brand, too!). I use Cream Cheese and Strawberry Milk. Each pencil will set you back around 4 bucks. The sales reps at Sephora make samples for almost everything they carry. Don't be afraid to ask.
One thing I've noticed in general is that my an eye is very sensitive to product. I used to be able to get away with drugstore shadows, but since the eye weight, not so much. In fact, I had to toss out a lot of my stuff and buy fewer things of quality. I can still use drugstore masacara and eyeliner, but that is about it. Even drugstore concealers irritate that eye! In general, I've had really good luck with LORAC and BeneFit. Clinique is really good, too--and much easier to find at the local mall.
