It looks like your choice is between that and Mepro tru-glo adjustables:

They both seem to hover around a similar price range, but I can't seem to find any reviews for the LPA, while the tru-glo's product page reviews on various sites are filled with glowing (pun intended) recommendations.
Frankly, the fact that you even have those two to choose from speaks to Glock's robust aftermarket. The large majority of people shopping for target sights are only interested in blacked out rears to pair with a fiber front, as that's what's in vogue right now.
