Rode mics are 'poorly designed'? Really? They are a common mic around here, and people are making some pretty good tracks with them. They aren't a Neumann or Telefunken, but most people that do this as a hobby can't afford to dabble in such esoteric mics.
Rode mics are perfectly good, and reasonably well designed for the price.
When I was an audio engineering student, I had access to a plethora of mics ranging from cheap to pro. Neumann TLM103 and KM184, Shure SM7B, AEA R92, Audio Technica AT4050, quite a few Advanced Audio mics, Electrovoice RE20, AKG C414 B-ULS, and more. I liked all the above mics, but quite often I'd grab a Rode NT2000 since it was quite clear, open, and predictable. We also had a Rode NTK and a Rode K2, both tube condenser mics, which we (both students and teachers) all thought were at least equal to the list above.
Sold quite a few Rode's in my day working at the local music shop, and never had a dud. Can't even remember any refunds on them either...
A neat trick is to vertically hold a pencil in front of your mouth just below your nose.
This is a great trick, though I prefer to hold the pencil on the mic with a couple elastics. It's best to change the mic position a bit - raise it up and angle it down - but sometimes that's not enough for some singers!
I tried that. Kept jamming the pencil in my eye!

They make those giant oversized erasers that stick onto pencils for just this purpose.
