For what it's worth, I have seen new Poulan mowers off and on at Amazon for $149 delivered. I state this because lots of buyers are going to check Amazon just to get a benchmark on NEW VS USED prices. Today, they have it at $219, but if it drops to $149 again, you have to be aware of this in your used pricing. I'd probably only offer you between $75 to $80 when I got there, if I could get a new one delivered by Amazon for $149. But you can always ASK for $150 and expect negotiations by the prospective buyer.
I also agree with Nwatson. Honda mowers are rock solid for what you pay. I'd probably go Honda before I'd go Deere. Not saying that J.D. is a bad mower, just saying as far as reliable 4 stroke walk behind lawnmowers are concerned, Honda is an incredibly reliable brand. In my business I use 2000 watt Generators a lot, and Honda Generators are absolutely rock solid. Nothing else comes close in that category, IMO.
Good luck!
