I would say if that is what is in your budget.. go for it. learn the tool...no master the tool. You will get great sound using correct techniques and basic tools. the Zoom H1n is adequate IMO.
You would do better w/ an H4N, but the H1 is acceptable. Im sure an Audio Pro would not rave about it .
I just got me an Olympus VN-8100PC, a $49us digital recorder and a Audio TechnicaATR3350 lav mic to use as a replacement for a wireless lav and it is usable for my needs. Still have to watch carefully, but the sound is certainly workable.
I would love the $$ for a pro setup or have the time to rent all the pro gear each time I shoot, but being a one man show, I need my gear always available.
