I'm in the same boat you are. I have a decent enough one right now but its just too big. I remember someone here suggested this one
Craftsman 16-gal 6.5-peak hp Wet/Dry Vac with Detachable 265 mph Blower - Model 17066 at Sears.com and I think I am going to pick it up tomorrow before the sale ends. The nice thing about it is it has a detachable blower so I wont have to buy a leaf blower too.
