I am finishing my CCNA and CCNA Security and was contemplation to go for the JCINA and possible the JCINS-ENT. I have the opportunity to pick up a J2320 with 1GB Flash/RAM and a Dual T1 card for $240, I know they are well worth more but do you think one would be OK for those exams? I really don't want to put too much money into it but I see how many issues people run into with the Olives and really don't want the headache

What do you Juniper Guru's think? Will that one get me familiar with the differences between the Juniper and Cisco hardware for some hands on and be able to use it to study those two exams?
Cheers
