It depends on throughput vs read length.  If you need to run more than
one gel/day,
get the 36cm plates as the 48cm plates need a 10h run.  If you want long
and are happy with 1 gel/day, get the 48cm plates.  We do a run or two
per week,
but use custom primers so want long reads (primers are expensive), and we
36cm plates as advised at first. After a few weeks I bought some 48cm
and we haven't used the 36cm plates since.  There is no difference in
ease of  
handling, and the gel reagents cost buttons, so unless throughput is a
big issue, 
ignore ABI and go straight for the long plates.  Also, we use ordinary
(Amresco), and regularly exceed 600bp of 99% accurate sequence with 48cm
I've never tried Long Ranger, but I thought it was for 373's.
