KT-18 ~$520 (2 ch) Mini-Z and dNaNo only
EX-5UR ~$1000+ (3 ch) Mini-Z and dNaNo only
EX-1UR + module ~$1300+ (3 ch)
EX-10eurus + module ~$2200+ (3 ch)
EX5-UR is better than KT18, it cost around $1000+ and it has 3 CH; and I think EX1-UR + module will be better than EX-5UR, because the EX1-UR + module cost around $1300+ and it has better 2nd hand value.
