Hey I just made my sqaurefoot garden but instead of drip lines or soakers, I found an irrigation grid. It partitions the garden into sqaurefoot .. sqaures. (haha) and surrounds the plants with a steady stream of water. I love it!
The company is gardeninminutes.com, not sure if that's something you are looking for, but definitely a nice change from all the mess of soaker hoses and drip lines. They also have expandable cedar raised garden boxes that are beautiful! Hope this helps.

i made mine from home depot drip irrigation stuff, and a bucket. Ran 3/4" polyethylene sprinkler pipe down the middle(you can get it in 3ft lengths, connectors are all over HD) and ran legs off of it with drip line(i think emmitters every foot) put a garden hose connector on one end, and plug the other. I hook up the bucket, fill it up, add fish emulsion and drink beer(or coffee, depends on when im watering) after about an hour, fill it up again.repeat as neccessary.

Like to tell you it works awesome, but everything kind of sucked in my garden last year(except anaheim chilis and jalapenos) I will say nothing died from dehydration, just a myriad of other things. I can try and get pics if needed.
