Get the D-2 only if you have the room for it. Your B-22XL is more than capable of handling everything you've listed. You may even be able to get larger prints with the XL than the D-2 could give, due to the extended length(hence-XL) of the column. If you plan on acquiring a 6x9 or larger then you definitly need the D-2, or just get it, and have a reason to buy more cameras in larger formats(yummm --more camerasss --biggerrr negativesss --ooohh yaaa). A rolling cart about the same size of the baseboare can be bought or fabricated to roll that bad boy around easily. You may just buy it to have more than one machine, so you dont have to switch around so much.
