Looking for an e-kit for practice

I've ready about the TD4 and some Yamaha kits. I need something portable, able to handle a double kick pedal and has coaching / training programs included in the brain.

What have you used and what do you feel is the best for less than $1,000?

Thanks!

Check out used kits , ie TD9 or TD6.

I only know Roland but Yamaha should be checked out as well.

Check to make sure the kick pad is big enough for double bass.

Where do most of you shop to search for used instruments?
