What do I want? I was on alamia and looked at the Billy Goat Lawn Vacs and want to know what the difference are between them. I see the first one on that page goes for about $995 and then there most expensive one goes for $2295 or something like that. Obviously there is a difference, but I don't want to spend more than I have to, but I hate buying something and having it not be adequate. I mainly want it for thatch pick up after power raking and leaf pick up in the fall. Which one will work for me? Thanks!!!
