I am looking to use a filter for the main purpose of protecting my lens. There seems to be a few different types, what would you suggest and why? Do the expensive ones have any real advantage over the cheaper ones.
 
I use hoya hd uv ones on my lens. If you search the forum you will see people have different opinions on filters.

Some say if you have a hood you do not need a filter.
 
There is a difference in quality between cheap & top of the range filters but whether you need one is another discussion altogether.
Me, I'm happy with a hood.
 
Some possible issues to look out for with cheaper filters:
- they can have thicker frames and on some lenses this can cause a vignette, particularly on wide-angle lenses
- they may not be multi-coated so this can increase the chance of lens flare
- light transmission may be more reduced than with more expensive filters. Even a UV filter that looks completely clear can reduce light transmission by a few percent but more expensive ones tend to minimise the loss

Hope this helps.

You forgot to add some can create a Vaseline smeared front element effect with 100%of your photos looking like crap.

Buy cheap, if you don't care about the several hundred pounds worth of precision engineered glass and electronics behind it.
