Two points:
-- Home vs. lab printing is different when you're talking scanned negs vs. old-fashioned wet printing. For wet printing, "print at home" is always better (once you've mastered the skills) because you get exactly what you want, vs. what some lab machine wants.
In digital printing, you're doing all that decision-making onscreen, so the real test is how well the printer reproduces what you see on the screen. A lot of that has to do with monitor profiling, and that's easier to do with a home printer. But if you're working with the same photo lab every time, and if their process is reasonably consistent, you can profile to a lab printer too.
In terms of quality -- nobody here is going to like it, but I've used many of the top inkjet photo printers (I have personally worn out an Epson Stylus Photo, Stylus Photo XL, and Stylus Photo 1280, and currently have an R800, plus the HP printers we have at work) and I don't think that any of them produce results as good as a good photo-lab setup such as a Fuji Frontier system. If your lab's equipment isn't as good, then your results may not be as good... but if that's the case, why not use another lab?
Having a home inkjet does have advantages such as being able to get a print quickly, being able to get large prints less expensively (if you buy a wide-format printer) and the fact that you can experiment with different paper types and finishes. But if you're strictly after quality, I think a good lab can do better.
Again, I'll bet you that nobody is going to agree with this. (But when they tell you I'm full of it, ask them how many photo printers they've worn out.)
-- Don't rely on what you "hear." Although the 2200 has gotten good reviews and a lot of people like it, it may not be the best for you. Like the R800 and the forthcoming wide-carriage R1800, this is a pigment printer rather than a dye printer.
Pigment inks are supposed to be good for longevity (although HP's latest dye inks seem to do just as well as Epson's pigment inks in Wilhelm's latest cabalistic tests) but they don't have quite the vividness of color, and their surface sometimes looks a little funny when light hits it at different angles.
Look at output samples from various printers (ideally made from your own images) and make your choice on what looks best to you.
