wouldnt be sure about that man, i think i need a decent mic for studio recording..
Hey, I named not one but TWO mics that are more than decent for studio recording!
The AKG D5 performs like an SM58 but lacks the 3-4 kHz "Shure Shout" has fuller bass and a nice bit more detail. Being a super cardoid, it also has better flank rejection, which rocks for singing without headphones. The SM7B (yes, I own one) is basically an SM58 with a chunky body and few extra tricks up its sleeve.
The sEX1 is a nice example of a budget LDC without the classic "Chinese OEM" hype. I haven't tried the Senn MK4, but I'd be surprised if it was really a lot better. In my experience you need to step up your budget to at least $500-700 to get an LDC that's significantly better (AT4050, Neumann TLM-102 and Shure KSM32 spring to mind).
I'm no pro, but I've tested a lot of mics. It's sort of a hobby of mine...
