I'm looking for a nail gun that I can use to do things like install door frames and to put up molding.

I don't have any air tools thus I don't have a tank. I've seen nail guns that take small air cartridges as apposed to ones that need to connect to an air tank. Would that be good for my needs?

I would like something reasonable, don't need the best/most expensive.

 

that is a tough one...

for the price you will pay for a cordless nail gun, it may be cheaper for you to pick up a small compressor and harborfreight finish nailer... and you can use the compressor to do other things like air for your tires, etc...

I'm going with the poster above and recommending buying a pancake compressor and a harbor freight nailer. I have a lot of harbor freight stuff and some has been good and some has been bad. The compressor and nailer have been great.
