I have never tried a slot it controller but have a truspeed mt I, mtii and apex. I would recommend them all, and the manufacturer is in the UK, so if you are too theres a lot to be said for that from a service/repair point of view. 

For 1/32 club racing  I'd personally recommend the MTii if you use any punchy motors (roughly 300g torque +) as the addition of the acceleration control over the MTi can be very useful at this point. If you have a live start track the launch control can be quite useful, for a few extra pounds worth getting to try it anyway. 

I think if you are new to club racing the apex would be overwhelming, it's a huge jump in complexity from an MTi/ii. 

Hope that helps, but if it's possible try before you buy as I know people who swear by a Carsteen at our club and I find them unuseable so it's very much a personal preference.
