You can build your own from a 5 gallon bucket if you can drill the holes. It uses a small submersible pump that sprays water on the bottom of the lid.
There are several pages on the web where people build there own on the web, so google should help, if you would prefer to do that.
The reason I mention this is that you can fill small net cups with Grow Rock (Hydrocorn), Lightweight Expanded Clay Aggregate (L.E.C.A.)

Then you set the cups in the hole, place a seed in them, and the water and o2 wick upwards to pop the seed. You then put it into whatever you want to plant into.
Or start them in recycled paper towels on the kitchen counter...
