For a Canon printer, the consensus favorite inks on forums like steves digicams and the nifty stuff forums
are MIS, formulalabs, and hobbicolors.
And I do not recommend you get the kit for the ip4200/4300 because one of the nice features of the hobbicolors kit for the ip4000 is that included in the kit will be five virgin cartridges with a factory made screw seal. You may even want to get an extra set.----since the ip4200/4300 cartridges are chipped these virgin cartridges are not an option for those printers.
In terms of the UW8 inks, you may well be able to specify them to be substituted for the other inks.
Hobbicolors is very flexible about customizing orders.---as a happy hobbicolors customer---I can tell you that as a fact---their communication is excellent.---and they are flexible.
But two items it helps to know going in---it helps to have or know someone who has a paypal account.
And shipping is very possible if you live in the USA or Canada---otherwise check first.
