You should direct specific questions on the CD26 to the CDSOA, they are a great resource.
I'd be more inclined to purchase a CD26 over a CD25, mostly because it's an Alberg design and I really like the interior layout.
Keep in mind, you could probably get a 27, 28, or 30 for that kind of $$, though. I'd go aboard them all, see which you prefer. I'd think long and hard about looking for a CD30 with that kind of $$ though.
