Tim,
I agree. I have the old stuff and they never get used. I use the 1554, 1440, 1864 and 2186 but none of the older ones. This is what I referred to as workers over lookers. That 1810 looks good as well as provides a nice deck for some mowing. I could probably get it for under $600 as well. I'm really leaning that direction because of the condition and usability. I hate being practical. It's this kind of thinking that's always kept me from buying a Vette!
Thanks everybody. With your help I think I'm declining the 70 and 100 deal and focusing on the 1810.
edit...I do use the 72 for garden plowing a couple times a year.
