start off with a diatonic harmonica, chromatic ones and other types are used for more advanced stuff.
The harmonica you have your eye on is a good one, i thought about getting one myself. I would reccomend you get a different one though.
The hohner blues harp has wooden reads. This helps you bend notes easily. BUT some players not used to wood cut their lips or tongue etc on the wood. ALSO begginers shouldnt use wooden reads to begin with, They are delicate and begginers who dont know how to control bends and general pitching propersly often break/ damage the harmonica after a week or two.
The honer marine band harmonica along with one other brand (sorry cant rmember of hand) is considered the best all round harp.
Having said that i reccomend you start off on a cheap, no name harp. Expensive harps are easier to break, especialy if you're a begginer.
Get one in the key of C as most tuitional material - books etc. - have all their material in the key of C.

Should I keep searching for a non-wood model then?
no, treat yourself get the honer just be carefull, you dont have to be forcefull
a word of advice though playing a harp (or any other lung based instrument one presumes) is all about having a delicate touch, just like slide guitar. It more about how much you dont play rather than how much you do------at least if you want good tone
heres a tip when playing the harmonica you shouldn't be "blowing" through the holes. The correct way to play involves altering the air pressure with your throat. I know that sounds downright odd and confusing but trust me you'll figure it out.
just be carefull, you dont have to be forcefull
