Unless you are building 1000s and also need less than 18 pins use an 18F 
series
do check the microchip site. A lot of parts in Web articles are very 
obsolete and projects can easily be done on newer pin compatible parts.

the 10, 12, and 16 have about 10 members each in pin sizes less than 18 
pins if you want small.

the dspPIC, 24F are different family.

the PIC32 is really a MIPS core.  Personally, if an 18F isn't powerful 
enough or enough Flash, etc, I'd use an ARM Cortex M1, M3 at low end and 
bigger A8 or Cortex A series with enough Flash & RAM for Linux at higher 
end. ARM starts at about $4

Check out JAL, Free, Open Source on Linux & Windows
http://code.google.com/p/jallib/

I've compared JAL to Hitech C, Boost C, Mikroe C and for PIC, certainly 
10, 12, 16 it's better.

Good, if somewhat out of date overview of PIC 
http://www.voti.nl/swp/index_1.html


Really seriously consider PicKit 2 (under $30) or Pickit3, else there 
will be PICs you can't program.

Some stuff on my site too http://www.techtir.ie/node/1003280

http://www.techtir.ie/node/1003375
I started with 16F877, switched to pin compatible 18F4550 and added USB, 
just with a header change in the JAL code and now I will do next 
prototype with SM TQFP 64pin 18F67J50, 128K Flash, as I have run out of 
memory on the 32K Flash 18F4550. All my existing JAL code and 
perpherials will work. Eagle has most of the parts libraries inc 18F67J50
