I've used the cheap flare tools with a bit of success but have since started having a local brake specialist cut and flare all my lines. I use coat hanger or similar to lay out the lines and get a length and take that and the tube nuts in and have them make up the lines. The line is higher quality and has proven to be more corrosion resistant than what I'd bought through Summit and the flares never leak. Stainless line is also an option if you want something that looks really nice. Just to be clear, this shop isn't one of the $99 four wheel brake places. They do mostly fleet service and do top rate stuff. Any decently large town should have something similar in the area.

Also, working in the OE production world, one of the tricks we use on leaky flare fittings is tighten and loosen the fitting 4-5 times in succession. Many times this will help a flare that's not quite right to get itself sealed up.
