1.	When you measure temp on test board locations, you should get the same temp. 
2.	When you measure the profile temp., there will not be a temp. reduction between zone to zone
3.	Friendly software 
4.	Possibility to change from oven to oven and getting the same profile results with the same parameters
5.	Fast change from profile to profile
6.	Smooth movement of the belt/net without any vibration

Don't forget about belt (i.e. lubrication) maintenance.

Hi Leland,

From a maintenance stand point:

Check on blower life and heater life.
Ease of changing both.

Get references for current users that have reached the claimed life
expectance of these items and verify manufacturers claims.

 Hi CH,
You do not want 'aggressive' ramp down rates-these cause pad cratering
among other things.

Hi Leland,
Depends on the size and thickness of your boards, you may need to
consider center board support. 
May also want to consider different cooling options if you need more
aggressive ramp down rate.
