get a shocker.
can pick them up for around £150 -200 and imo better than a pmr (and yes i have owned both) and much lighter than the speed.
if its definatly between the 2 then i would go with the speed, simply because it recquires very little maintenance, it is a high end marker, where as a pmr is more a mid range, the pmr has plenty of things that can be upgraded but a speed already has it all to start with.
if you can try both before you buy
