I've had an LSD with F5 arm in my system for 3.5 years now, I think its a brilliant deck. Setting up isn't too difficult and its been nothing but reliable from new. On the odd occasion I wanted some information/advice I managed to get in contact with Arthur at Funk and he was super helpful, he even called me to see if everything was ok. The stability is night and day over other belt driven TT's I've owned. Personally I think it punches well above its weight in this cost bracket.
Everyone who has listened to my deck have commented on how great it sounds (they could just be being polite of course). Its not the obvious choice either so not many users I see on this or other UK forums.
In comparison prior to the LSD I had Rega decks, firstly an RP3 and then RP6 both new both had issues. The RP6 was bought because my RP3 had issues and a deal was done to replace with the latter. The cart that came fitted on the RP6 was faulty and again Rega resolved but I haven't had any of those issues with the Funk.
