Anyone have a recommendation for a reputable source for keyless entry remote fobs?

I'm hesitant to order from random Amazon third-party sellers or random websites with questionable reviews that come up on Google, but the $20-30ish pricing found on those sites is quite attractive compared to the $149 price at the stealership (not even sold anymore, apparently, but they still show a list price). Ace Hardware will sell me one but it's the same $149 as the dealer list price.

Anyone have a recommendation for a reputable locksmith or key fob seller? Mine's a 2000 Maxima that I'm 99% sure uses the one with FCC ID NHVWBU43 (original was lost/stolen several years ago). Local automotive locksmiths are proving frustrating to deal with ("we don't have that one in stock," not being willing to order, etc.), so online seems to be my best bet, especially since self-programming seems to be pretty easy.
