I like Dual, I have a 704, excellent table also had a 1229 also excellent.
Never owned a 5000 so can't comment on them.
I have a Thorens 145 MKI, slightly different then the MKII, namely the arm and amrwand. The 145 MKII will accept high compliance cartridge (mm) and a few high output MC cartridges.
If you get the Thorens, you wont be disappointed, it's an excellent table, good quality tonearm, platter and overall mechanism.
