(ET) Vacuum or Sweeper?

["T Humphrey" <thumphrey mynra com>]

Greetings Folks.

Well Autumn is upon us for a couple days b4 the snow season sets 
in.

Does anyone have an opinion one way or the other concerning the 
pick-up of leaves. Should I build a vacuum or buy a sweeper.

A vac would be kind of like Dennis Pestka's

A sweeper would be one like can be had from any hardware or box 
store.

If I build a vac, it would be different from Dennis'. I was 
thinking of using a blower or fan but it would be downstream of 
the filtering so no crap goes through the blades. Much like a shop 
vac. Of course no mulching gets done as with Dennis' set-up. Does 
anyone know if a blower or fan would be the best choice in such a 
set-up to develop vacuum? 

Of course a sweeper would use less power but a vac would do 
a "better job" I believe. But I have no experience with either.
