With good PA my HEQ5 pro will do 60 seconds unguided with a 100mm F9 refractor.
Or perhaps a second hand laptop if you can get one cheap enough.
If you are good at making stuff, there's manual guiding with dual refractors where you do the guiding. I made guidescope brackets out of toilet seat bolts and some wood. I made a guiding eyepiece out of an old binocular eyepiece, some film and a red LED. But then I'm a duct tape engineer.
