Diesel Bombers - what chippers do you guys have?

with in the last month i have picked up 2 small chippers.

one a vacuum/chipper troy built 8hp briggs takes up to 3" or says so in the manual
and one 5hp briggs yard machine has a hopper for leaves and shute for sticks takes up to 2 1/2 but will take what ever you can fit in it.
i'll see if i can get some pics up.

the yard machine is GREAT! 5hp hands down my favorite just wish it was bigger.
the troy built retailed for $1800! new i bought it in new condition.
it chips bigger stuff really slow and i just do not like it at all.
i buy this equipment to resell it, i seem to hold on to stuff more then i sell it LOL
i have found a chipper to be very useful, witch i never really realized until i bought one to resell then figured i would try it out. but i would like something bigger.
maybe sell both for one big nice one?

what do you guys have and what are your opinions?
