[Blindtlk] Deciding between Perkins Brailler models and sources to buy

[Gerardo Corripio]

Hi guys: After nealry twenty years of using my Perkins, it finally gave up, 
thus I'm trying to decide whether to buy the classic Perkins model or the 
newer one that's 40% less heavy and redesigned. What have your experiences 
been with either of these in terms of guarantee from the manufacturer, 
durability (I use my Perkins a lot to transcribe questionaires I apply to my 
patients and other notes )and within the machine's overall functioning? and 
the difference in price between both models?
Also, what places do you recommend to buy Perkins? I'm aware in searching on 
the Net that the NFB Material Center sales them as well as buying directly 
from the Howe Press in Boston. Which of these two places is better?
Thanks in advanced for any info.
