I have an OTA what's the cheapest mount + GOTO combo to get?

Hey everyone! I already have my OTA and I'm looking to build the cheapest possible setup to get full GOTO tracking without breaking the bank.

I've been looking at the Sky-Watcher EQ3-2 as a base mount paired with the Maxgeek V5 EQ3D Pro OnStep kit (~€178 on AliExpress) as an upgrade, but I'm not 100% sure on compatibility with the EQ3-2 specifically. Can you guys give another mount or goto to buy?
