Hi auwillie:
A Lincoln 1452, in my opinion, is as good as any Air impingement oven of the same age.
What is the year the oven in question was manufactured?
Has the unit been rebuilt or is it just a used oven?
What is the size (length-width) of your hood?
If you would like, I can give a better assessment of the oven with the above information.
