Good microphones for recording acoustic piano

what's your budget?  acoustic piano is difficult to record well.  here's what I would love to have for acoustic piano, but there's no way I'd be able spend that much money on it

the next thing I would consider would be something like what this guy is doing:

he has an LD condensor and a boundary mic

Also, I will be recording onto my laptop PC with a cheap onboard sound card.  I will then copy the .wav files onto my desktop PC with a SoundBlaster X-Fi Audio card so I can add more instruments and sounds using HS7XL.
 
Should I replace either of the sound cards?

YES.  you should replace both of them.  look at my website for soundcard recommendations.

Thanks Beagle for your reponse, advice and great links to more info.  I'm new at this, so I can use all I can get.  BTW, my piano is a 6' Kawai.
 
I went to your website to view sound card recommendations, but coud see no content where I assume the recommendations would be... ?  I even clicked on the "Click here..." button, but still blank.  My laptop being funky??? 
 
Thanks again.

Can anyone recommend which condenser mics would be best for recording acoustic piano?

 
FWIW, A pair of AKG C414s will do an excellent job recording acoustic piano...
But I wouldn't record them using onboard audio or a SoundBlaster.  
 
The point I'm trying to make is that it doesn't make sense to invest in quality mics if you're not going to have a commenserate level audio interface (and mic preamps).
 
I'd start with a decent audio interface... and (if you're on a budget) look at a pair of Studio Projects B3 mics.
Note that a decent audio interface need not be overly expensive.  $180-$500 buys a pretty decent audio interface.
Choose based on your I/O needs and budget...
I'd suggest going with a proven rock-solid unit.  Aside from the PC, the audio interface is the second most critical choice for a trouble-free DAW. 

There is a recording of an acoustic upright piano (done at my local church) on my website called "Be Unto your name" and it was done with just a pair of Audio Technica 4021's great pair of pencil condensers

Here's the link

Aaron - that's pretty good for an upright!  oh, I love that song!  where did you place the mics?  was the piano up against a wall?  one method I tried mic'ing an upright was pulling it out from the wall, pointing the matched pencils toward the back of the piano about 1/3 of its height from the floor and about 1/4 of the way from the outer sides, pointing directly straight, with 90* angles to the floor and the piano.  it wasn't bad, but not as good as the recording you have here.  I do hear a little of the room in your recording as well, tho.

sogoodwin49 - my opinion is yes, you would want to replace the soundblaster and you CAN mic a piano, obviously, it just depends on what you want to do with your recordings, too. 

if you want to record MIDI (like I do and a lot of us home users do) and use a sampled piano then you'll also want a good sampled piano.  those are not cheap either.  some of the best ones are IVORY, KONTAKT CLASSIC PIANOS, GARRITAN AUTHORIZED STEINWAY and I'm sure there are MANY many others, those are just some of the ones that I'm fond of.

thanks for sharing!  it's really pretty good for an uprigtht recording!
