>>266206the ones innapic are Nady cm-100s. they're cheap but very flat. they're primarily used for acoustic measurements and the like, but being omnis they're great for nature/ambient recording. because they're pretty inexpensive they are a little noisy but i've gotten very good results nonetheless.
it depends on what kind of recording you're doing though, omnis (much less a pair of them at once) aren't often the best choice. also, pretty sure you won't be able to find a matched pair of the Nadys... they just don't do that
