Printing...do you do your own?

or do you get it done professionally? I'm talking about getting those larger prints done, and your landscapes especially. After all, looking at them on the monitor is not the same as having a beautiful framed photo on the wall.
I've got a HP photosmart which does A4 with surprisingly good results. Is it worth getting a good A3+ like the Epson 1900 for 13" x 44" (off a roll) landscapes? Does anyone do this (initial investment plus ink costs are a bit of a sting) or are you happy to get them done elsewhere? or just satisfied to look on the screen?
