I probably need to get a new egg beater and had considered the Stradic CI4+ but if I order the newer Sustain FI from Digitaka it comes in around $230 which is the price of the Stradic. Or should I pony up and get the Excence which would be around $420 from Digitaka. Anybody here with experience using the new Sustain or the Excence? I've read some say the Excence is actually smoother than the Stella FI and they share the same body with the Excense having a lighter spool, seems the Stella has a coating on the drive gear that wears down and becomes "grainy" Also read a few saying the new FJ Stella is nothing to get excited about vs the previous FI model.
