Take a look at Hart Dynamics... made in my hometown!
http://www.hartdynamics.com/

Give them a call or email, talk to Paul Andre (sales manager), mention my name, and get the straight skinny. These guys are endorsed by many of the best drummers WHO ACTUALLY USE E-DRUMS (not just endorse them!), and have a wide variety of price and product ranges...

I have had a kit of theirs for years, very reliable, very sensitive.
