I have done both wet darkroom (B&W only) and my own inkjet printing.
I have avoided using wal-mart, cost-co etc etc.
I enjoyed the wet darkroom, but it took time and effort, which I had more of many years ago.
I really love the inkjet printing. I can manipulate faster in LR and CS than in the darkroom. I never compared costs, not sure I remember enough at this point -- but I produce many more inkjet prints than I did darkroom prints, so it might not be a fair comparison.
I bought an R2880 (Ernesto's recommendation) just before the R3000 came out. If I were doing it now, I would go for the R3000, its newer and uses the larger ink tanks.
I love the 2880 -- it cost me $699 less a $200 mail-in rebate, so $500 - and was well worth it.
Not only do I have more control than if I went out for printing, but I can get prints instantly! before other people do -- e.g. during a family get-together I can hand out prints before the party is over!
