The 3800 is made for you!
The 3800 form-factor plays friendly in a typical small home office or den - quite light enough and compact enough, whereas basically all other 17" printers are fork-lift-heavy, room-devouring monsters (only a slight exaggeration here).
I moved from a 2200, and the improvement was a miracle. Essentially zero clogs, too. Moving from a 2400, the transition will be instant and painless, with no learning curve at all.
As far as roll capabilities go, I for one hate dealing with curl. I'm so happy to have a wide variety of cut flat sheets for 95+% of my work. For the other 5% (stitched panoramas), the 3800 takes up to 37" sheets, which I cut from a roll and feed manually. This is wide enough for typical stitched panoramas (e.g., a single row of 5-7 frames with the camera turned on its side). It may take a few tries to get feeding long sheets down, but after that it is easy.
The ink tanks are just the right size for you as well. Much larger, and you will have 2 year old stale ink in your tanks before you use them up. On the other hand, they are big enough that you will be delighted with just how many prints you can get from them, especially after moving up from those dinky 2400 so-called tanks. Figure you will start replacing your first tank or two in 9-12 months. If you don't switch inks daily, the switching is fast and economical enough not to matter, especially compared to quality paper costs, etc.
Going from a 13" printer to a 17" printer is a revelation - it seems like acres of more paper! And yet the 3800 feed down to 4x5" paper. All in all, 17" is a great size for most advanced amateurs.
Really, for the typical advanced amateur with a modest home-office space, the 3800 is still the best printer available.
Just get one.
P.S.: (1) It is not a conspiracy that cut sheets are hard to get in 25" lengths. Available sizes are long-standing industry standards, and longer sheets must usually be cut from rolls anyway. (2) Note that in the 17" sizes, some typical papers, e.g. Epson Luster, are too thin for framing without being glued to a backing board. If not, they have a wavy surface that is distracting. For 17" sizes, you should go with 300+gm papers such as Velvet Fine Art and Illford Gold Fiber Silk (both wonderful).
