Film scanning abides to the "affordable, fast, good quality: pick two" rule. These variables have particularities of their own, such as what you and I consider affordable may differ greatly. Flatbed film scanning is indeed affordable, and can lead to pretty good results for web and small printing. The Epson V700 and V750 scanners are a good bang for the buck, as they offer quality scans for around $600. I've seen great images scanned with the V700 by Portuguese landscape photographer Nană Sousa Dias
The main problem with film scanning is speed. Not primarily that of the scanner, but of the whole workflow. If all cleanliness aspects of the film are followed – no fingerprints, marks, dust – which is something that even the most tidy laboratory worker has problems, it can take anywhere from thirty minutes to two hours to get a decent, well processed scan good for printing. Remember that no scanner can remove dust and scratches from silver-halide black and white negatives, so spotting and retouching is inevitable. Multiply all that work by twelve exposures, and suddenly you find yourself spending more time in front of the computer than outside taking pictures.
Considering that you want to develop in-house, add up all the effort, time and expenses of chemical mixing, storage, and darkroom maintenance. If you shoot sparingly, you might want to gather a couple dozens of rolls to develop all at once, and thus use fresh chemicals rather than keeping them stored for extended periods of time. In the end, it might be actually faster to have them processed externally than doing it at home. Of course, if the personal involvement aspect is of great importance, none of this will matter.
If you have a complete darkroom, with development and enlarging equipment, I suggest sticking with contact prints and small enlargements. If a picture deserves a large print, send it out for drum-scanning. Though you pay the steep price, the quality is worth it and the hassle is minimum. If you don't have an enlarger, the Epson scanners might be a good starting point, though drum-scanning may be needed for large prints.
In the end, when you think it'll take a couple of minutes and some effort to scan film, you actually find out you've spent the last two hours trying to get it right, you've neglected your spouse or family member's cry for attention, the magic hour lights are long gone and all you do is curse Adobe. I like going through that some, but not all, times.
