Vince, take the plunge on the Zu 103, it beats the stock 103, and is well worth the money ($800+). I've gone on to get the Expert Stylus And Cartridge Company here in the UK to mod it with Paratrace stylus and White Sapphire cantilever for £280 ($450+). It comfortably outpaces my 4x pricier Transfiguration Orpheus. An unbelievable giant killer that I would not swap out.
I have a thread devoted to the Zu 103 ESCCo mods.
