I can't make specific recommendations, but I do have a few pointers:
• Generally speaking, when you set up a new printer a lot of ink will drain from the cartridges to "charge" the system — fill the lines from the cartridges to the print head.
• That said, high quality photo inkjet printers use a lot of ink. That's why some pro models have extended ink systems with quart bottles as feeds.
• I find your planned usage interesting. Printing 6x4 prints is more expensive at home than at your local photofinisher. Print the vacation snapshots outside. For larger prints you may be able to obtain better results at home where you can print and tweak.
• I no longer print anything at home but still recommend Epson.
