Honestly I don't think Spektrum will be any better than the TS401, for small to medium size tracks running a 2S LiPo, I never once had a glitch. They were selling for $99 new with fire sale pricing when RP announced they were going out of business... so my guess is the system might be worth between $50-$75 depending on condition? Gonna be hard to sell for a radio with absolutely zero product support, who knows it might be a collectors item someday since it was the very first radio on the market with a color screen?

If I was going buy a new system for myself today I would get a HiTec Lynx 4S, there are several pro level drivers running that system in my area and they absolutely love that system, more info here worth considering:

Which surface radio system is the best?
