I have a T150 and have been using it for around 18 months (bought around Christmas 2017 when I got GT Sport).
Use it for a few hours every week, no problems encountered, except for shortish plug wire to socket and from wheel to PS4 USB. But not a problem unless you've got a massive room to use it in!
I think I paid £120 for it new on a deal. If the Pro is available new for £150 these days, then that sounds like a better deal than £100 for second hand, unless it's "hardly used" T150.
Nothing, however, beats the T1000. That is made of liquid metal and will never, ever stop, until your dead.
Hang on, I'll be back...
