OK, there's been a number of posts about this, so:

[quote author="hollywood_steve"]If you are going to spend dozens or even hundreds of hours designing and building your dream mic, wouldn't you want the best capsule possible?[/quote]
Yes, I would. Then again, who's talking about "dream mics"? It would most likely be pretty stupid to put a Feilo capsule in your dream mic!
There are a thousand different factors involved in DIY'ing; making the best-possible sounding gear is just one of them: Some of us enjoy the process. Some of us are only trying to learn audio electronics. Some of us like the smell of solder. Some of us are experimenting so we can make our dream gear in the future. Some of us have an urgent need for something specific. Some of us actually like the sound of some piece of "crappy" gear. Some of us like to learn **** the hard way, or want to put to the test what others post online. Some of us are just plain broke, but can't shake the DIY bug...... I'll stop.
The point is that a $500 MBHO capsule and a $20 Feilo capsule both have their uses. Like a Ferrari F550's and a Ford Pinto, if you like.
