hey nwb, welcome to the board!
I am also a college student so I know how you feel. I too spent way more at this site then I could have ever imagined that I would. Try not to bid on items that you haven't ever heard of just because they are good deals. I did that when I was new to the sight and it resulted in a lot of crap that I won't even smoke anymore. Spend the extra couple of bucks and go for the good stuff. As far as the cigars you mentioned, I have smoked the don lino's and the TH's and both are pretty decent everyday type smokes. If you're looking for more budget smokes, I recomend: 5 Vegas, Cupido, Mayorga, and La Rosa Especials. All are pretty good and can be had for around $1-2.
regards, Bill
