I would defiantly get the 3525 if i was going to get a FEL. No power steering on the 3325 would be a major problem IMHO I have a 3525 with FEL and gave about $14000 for it 2 years ago.
I paid 13500 for a 3525 and it is allot of tractor for the money I regular knock down large trees with it. the ps and 2stage clutch is absolutely worth the little extra. I do own tractors without it when mowing the 2 stage is necessity.
I was told by my saleman that they don't sell the 3325 with a FEL because it doesn't come with power steering. I got the 3525 with FEL, box blase and brush cutter for a package deal of around 14500.00 about 2 years ago.
