More of an instant type myself. Plus I'm a good 30 miles from the nearest Kinkos and stuff. 60 miles round trip. $6 x2 for delivery and pickup, just for the gas in vehicle, plus 2 hours or more in total travel time. You probably want a color laser printer. Inkjet prints bleed if they get wet. And because they are wet at the time of being printed, the bleed factor keeps them from looking all that great.
I want something in the 1200x1200dpi range myself, but it seems like most end up being 2400x600 dpi at best. 600dpi for sheet music is kind of hideous, especially if you have to shrink parts to put into a flip folder. For CD / DVD labels and stuff not all that great either. Depending on what you're printing. I tend to use povray to do my layouts and fancy graphics with pixel accuracy. So pixel perfect circles at 6000px x 6000px still look pixelated at 600dpi. At 3000px without the oversampling / bit-bucket it's far worse to include those strange lines and patterns you'd get with digital drawing at low resolutions.
Unless you do a lot of prints or don't live near a service. Then using a service is probably the better option. There are a number of decent options near the $400 range for ownership. But replacement toner will likely cost as much as the printer. I don't know if laser printers suffer this, but if my inkjet sets a while between prints (week+), I have to print a couple of pages before it starts doing good prints again.
