I was wondering what hobby condensor microphone (not eletrect microphone) could I use with the arduino, I was thinking this one from radioShack could work, (http://www.radioshack.com/radioshack-pc-mount-condenser-microphone-element/2700090.html).

Here's an electret microphone from adafruit, who seems to understand electronic gizmos for hobbyists: http://www.adafruit.com/datasheets/CMA-4544PF-W.pdf. The one you located at Radio Shack looks substantially similar, except that its sensitivity is 20 dB lower. That says that your amplifier gain will have to be about ten times higher than it would be if you used the adafruit product, for the same output level.
adafruit claims that they get about 1V p-p with their microphone at a gain of 125, with normal speech at 6". You'd either have to manage with 0.1V p-p at a gain of 125, or go to to a gain of 1250 to get 1V p-p. Gain like that, with an op amp, can be troublesome. It eats up too much gain-bandwidth product, and will probably make you go to two-stage amplification. But, it's feasible.
It would work. But, for sheer convenience, you might prefer the adafruit adjustable gain electret board, here: Electret Microphone Amplifier - MAX4466 with Adjustable Gain : ID 1063 : $6.95 : Adafruit Industries, Unique & fun DIY electronics and kits.

What have you got against eletrect microphones?
I need to compare the two together.
Of course, the Radio Shack element is also an electret condenser.
DVDdoug:
... the Radio Shack element is also an electret condenser.
Indeed. I overlooked the fact that the OP wanted to avoid an electret. If that's really a concern, the Radio Shack device isn't what he wants.
yes i would like to find a nonelectret condenser microphone.

I don't think that is going to happen in a meaningful way using an arduino.

Assuming by "hobby" you are looking for something "cheap", I don't think such a thing exists. 
I did a search for "condenser microphone capsule" and I found [u]microphone-parts.com[/u], but it looks like it would cost you more than $100 USD to build a condenser mic. Maybe you can find a used one (or a broken one if you just want to use the parts) on eBay for under $100???
It may be challenging to find a condenser microphone at an attractive that's not an electret unit. I find inexpensive models on ebay and elsewhere, but I can't verify that they're not electret units in a fancy package.
Electret microphones can be made with excellent characteristics, inexpensively. I don't see that there's a real market for non-electret units at the low end of the price range.
Will you share with us what aspects of the two types of microphones you want to compare?
