Can anyone elaborate on the difference between the 4263A and 4263B model ? i am considering buying one and have a offer for a A and a B model however the B costs substantially more $$$ so im trying figure out if its worth the money !
I'm not an expert on this product, but a quick check says the A version was obsoleted about 23 years ago and is out of support life, and the B version is currently shipping and supported, so if you are looking at buying on the used market, obsolete products are often substantially cheaper.
