Some people recommend using a paint brush like the Purdy XL - Glide brush which is made especially for trim work or the Purdy XL - Cub which is great for tight spots. The only thing is you need a steady hand and you have to take your time in order to get good results.

Since I don't have a steady hand and I'm not very patient, the Shur-Line Edger changed my life.
I edged my entire kitchen using this tool and since I'm vertically challenged it was great and edging over the cabinets was a breeze. Plus, for less than $6 you get a huge bang for the buck. I won't be painting without it ever again. LOVE IT!

Here's some tips that make you use it better
- Purchase extra pads, you'll need them if you're painting more than one day. I don't recommend you using the same pad the next day as the fibers will start shedding from the pad.
- ALWAYS remember to flip the wheels before you dip it in the paint.
- Have a damp cloth ready to clean off any paint along the back on your edger.
