Looking for advice

I have squared baled a lot of hay over the years but never owned a round baler. I am looking to buy one now and I am only going to roll about 500 dry fescue rolls a year. I have narrowed it down to two used Vermeer balers I like. So I need some advice on which one I should buy. The first baler is a 94 Vermeer 504i silage with new belts and hydro tensioner. The seconded baler is a 97 Vermeer 504superI with 3 year old belts, spring tensioner and is about 1500.00 cheaper. Both manual tie. Both balers are in great condition

Any advice on which one is appreciated.

Thanks
