Being the housing has a hole, probably cheaper to buy a used, plus you can keep your other one for parts in case you ever have probs again.
If buying a used one, visually inspect the outside of the unit. Pull the drain plug and inspect the lube, especially the first stuff to come out for water, metal shavings, or other junk.
Compare the prices for a used vs rebuilt. If you search C list or post a local want ad you can probably get a better deal than something marked up to full price from a dealer's bone yard.
Good luck,
