Differences between model years of FEC's

I would make sure the older ones are cheaper, they're probably been used more.

The slight variances would be where the pellet chute it (doesn't make a difference) and there were some changes on temp probe and ignitor, all not really an issue for what you're asking.

Look at them inside and out. Look for a bad rubber gasket (if there was a fire it usually shows up in a broken/bad rubber seal around the door.

Check the fan(s) and make sure they're working.

IF it was me, and the prices are the same and they don't want to come down, buy the newer one.

No issue with the size of the pellet hopper, even the older ones would run a LONG time on a full hopper (unless you're running at 400 and then they burn a lot)

My FEC100 is a 2003. One of the first built by Eddy and Cookshack. Still running strong with all original parts. I love it.

There might be some difference in rating to use it inside a restaurant,if that was a factor.

I have more info on one of the FEC's. It's a 2005 upgraded with an IQ4 controller in the summer of 2008. The 2005 FEC100 uses an auger and does not have the newer pellet shoot.

There is only a $300 difference between this one and ones that are a few years old. Does anyone have an opinion that could steer me in the right direction.

Friend of mine upgraded his "non-ramp" FEC100 to an IQ4 and loves it. I like the older model because it doesn't feel top heavy moving it around like the ramp models do. I'd look at all the other factors of all the models, especially state of the gasket.
