Avenuesound.com has the viper 4103vx for $59+shipping if you call and ask for it. Ive bought a dozen or more in the last month

1/4mile range. 2 - 1way remotes.. Its basic but has lifetime warranty and i havent had any issues with any of the ones ive put in to date. The python 4103 is the same remote start just python version.

If you want a 2way unit he described it pretty well.
