Eyepiece mystery

It's becoming increasingly clear to me that the key to making the most of my telescope will be the eyepieces that I choose to purchase for it.
I've been asking around on the forums but no one can really give me any solid advice on what to buy except that it varies from person to person and of course, the more you spend the better you get. Sadly this doesn't really work for me since I have no money to spend on eyepieces so cheap and cheerful is all I can go for.
I spent some time last night viewing various things in the sky such as Saturn and various star clusters just to try and get an idea of what I want to improve to get better views.
As far as planets are concerned, it seems like I'm lacking magnification. Saturn just appears too small for my liking so a good bet would be to go for a higher magnification eyepiece. In terms of Deep Space Objects (DSOs) I can only think that light pollution is stopping me from getting anything like a good image. Once I get out into the countryside hopefully I can start to judge what eyepieces I need for DSOs....
