Sounds like OP wants to be able to print photos occasionally. If only rarely, a photo processor in stores will be able to print them better than consumer inkjets though.
Out of the three machines in the OP, PC World has the PIXMA MP490 in their
current top 10 list, and it is the only budget all-in-one on that list. However, it comes with the caveat that ink cartridge cost could be high if you print a lot. A fact no doubt exacerbated by having a tri-color cartridge. The MX330 is rated lower with the same caveat.
At this entry level market segment, manufacturers low ball on the price of the machine and make profit on the supplies. You can defray some of these cost by buying third party or refilled cartridges.
On a per page cost basis, b/w laser can't be beat. I just refilled my Brother MFC's toner for $18 that should last me 5000 pages of output. Add the cost of paper, about $3 per 500 sheets, the per page cost is still less than 1 cent. At the same time, I also got some ink cartridges for my Epson R340, mainly used to print CD/DVD and photo. A set of genuine cartridges would have cost $70, and a set of third party remanufactured cartridges cost $20. I would be lucky if I could get 100 prints out of them. The original cartridges lasted around 50 prints.
Another argument for laser: When you don't use the printer, toner does not evaporate into thin air like ink does.
