Does anyone have any cheap ideas for raising the resale value of my home?

I am going to be putting my house on the market soon to relocate. Its an older 2 bedroom home. I can't afford to do any expensive remodeling (ie`new kitchen counters, gutting the bathroom). So I was wondering if anyone had any tips for what I should do to attract buyers. What are the big turn on's and turn off's when you look at a home. This is the only home I've ever bought so I'm feeling a little overwhelmed. We have done some updating while we lived here, but its all been plumbing, wireing, the type of thing you can't see. I'm looking for more cosmetic type advice. Thank you!
