IMO, forget the Kplete.9
Ultimate, instead
I might go for Kplete.9, and the upgrade is $149, .... But for newbies it's $559 for Kplete.9, in that case there might be a sale in future?, should I hold my breath?
Another option, wait for Kontakt.5 but I think it might sell for $499 rather than $399?, oh well I'll wait and then weigh up the options.
Sometimes it'd best to wait, don't rush, take your time, be patient, weigh up all the pros and cons, make sure the sharks and crocs aren't around, see if Shirley has a greater offer and then take the dive.
