I was having the same debate with myself before I settled on just using picnic taps for now, and then when I have more cash I'll just buy the one that I really want with the proper taps.
I also remember reading something on here about making one yourself with a PVC tube and faucets. I can't remember who had that posting though. I'm sure you can find it in the DIY section.
