Could well be more expensive depending on what parts you might already have for sure.
Let the Internet be your friend while shopping, I found an eBay store in Edmonton that had $30 items for $10 and still do.

It could only be more reliable because NO power inserter is required, that may be a plus or a minus, depends.
If it fails, It's unlikely the whole thing would go, so you can repair it by pieces as opposed to being totally off the air.
