DR vs Billy Goat lawn vacuums

[Mikey1959]

I'm sure this has been discussed before, but please bear with me. I started my own lawn service last fall, and need a walk-behind lawn vac. Most of the lawns in my area are 1/3 of an acre or less, plus a lot of trees. There is not enough room for a rider and town-behind vacuum. I've spent a few hours comparing the 2 brands, but still can't make up my mind. Which one will work best?

Thanks,

Mike
