When in doubt I go with what works. I often order Dexta parts online, only because my FNH dealer is way out of my way (30 miles from my house). And I work 1.5 hour away, and simply cannot get to FNH (now 60 miles away) without taking time off from work. If prices were within a few dollars, and FNH close, I'd buy all my parts possible there. My FNH dealer still gets high marks for customer service, when I can get there to buy the part. Will online offer free return shipping if the part is wrong?
Customer service is valued. I don't like talking to machines, and to people who can only read what I am reading. Wrong parts don't fix anything.
My 2 cents
BTW: I have quite a few wrong parts less than $5 parts (mostly seals), and it is not even work the effort to put them on eBay on a $5 part. Buy it. Own it.
