Cheap scopes skimp on all of the bits you need to be precise to get F4 to work well.

My 2 cents.
I went through the same slope as well. dslr was too noisy, so got a qhy8 cooled osc ccd, works without darks.

you're right, F4 needs precision but can be tamed.
a low profile sturdy focuser, low profile OAG like the TS-9 or a guidescope, correct secondary, cats eye kit, mpcc, cooled ccd. I reckon that's a workable combo.
