Single Tek, Laser Tek, Tek 3, Tek 4, Tek 5, Tek 6, Rapid Fire Tek, Air Tek 8, Clip Tek, Tek 10, Transforming Tek.

So far there's at least eleven of them. I own (or at least did own at one point) a Tek 3, 4, 6, 10 and Rapid Fire Tek. None of them are great blasters.

Also, there was the cancelled Pump Tek, which was discovered on an old NerfHQ page I think.
