Mine’s the 2004 Loreto reprint of the 1957 Benzinger Bros. edition, ISBN 1930278462.
The 1957 edition came out as a reprint/revision of the 1937 edition.
If you’ve got tens or hundreds of thousands of $$ burning a hole in your pocket, you could probably pick up a 1744, 1791, 1814, 1826, 1830 version pretty easily.

Probably not bilingual, though.
Various indulgences, etc, have been redefined/abrogated/whatever multiple times since then, so it’s probably not a good idea to take those at face value if you pay a lot of attention to those sorts of things. That being said, I recommend abebooks as one of my favorite vendors of vintage books.
As far as my edition goes, the cover and binding are excellent; the paper quality is very good; the type is larger and bolder than you’d normally see; the layout/typesetting for the bilingual aspects and citations is quite decent; it’s nicely triple-indexed; and I’d say it’s very well worth the $25-$35 you can expect to pay for a new or used copy. It’s not a cheaply thrown-together book.
