Oh, just learn to deal with cottered cranks! It's no big deal, and a properly adjusted / greased cotterless BB will last more or less for ever. Take a look at the "$16 cotter press" thread, or any of the threads that describe how to service cotters with a vise or even a C-clamp. Just don't use a hammer, and you'll be fine.
Changing a Raleigh cottered crank to a cotterless one can be complicated, depending on the BB of the bike. Raleighs used different BB threads (26 tpi rather than 24 tpi) and wider shells than most cranks. So to change to a cotterless crank you need to find a certain spindle that is getting increasingly diffficult to find.
