Tool for cutting vinyl siding?

I need to install a vent from my bathroom through my vinyl siding. I did the same thing for a dryer vent, and it worked out OK, but I had a heck of a time trying to cut a circle in the vinyl siding. I tried to score it with a utility knife and ended up holding a jigsaw up to the siding (I'm not too bright). What's the best tool for cutting a hole from the outside in vinyl siding?
Thanks in advance for any suggestions.

you could used a hole saw.
it's a round saw you can ajust to the size you can and fits on a drill

I use a hole saw on a drill and have done so up to a 4 1/4" hole.

The finer teeth the saw has the better and you need to be very carefull because the bit tends to grab.
I have found that duct tape applied just outside of the cut helps stabilize the siding.

When putting dryer vents through vinyl siding, one should use the appropriate vinyl siding accessory, made just for dryer vents. It has a nailing fin and a snap-on cover. You unzip the siding, drill your round hole with the hole saw (through the sheeting and drywall, but not the vinyl siding)... install the dryer vent flat against the sheeting, flash it, then you cut the vinyl siding with a tin snips to fit around the accessory, and snap on the front cover.

Drilling a round hole in vinyl siding and installing a dryer vent meant for a flat surface will certainly work, but it's not professional.
