The speakers really don't matter as much as a reciever/amplifier combo would.  You need to make sure the reciever/amplifier can process Quadrophonic sounds, then they have 4 speaker outs and then you plug 4 speakers in. I don't think they have even made quadrophonic processors since the 70's.  If you are talking about Surround Sound, they make those today and they process quadrophonic sounds to send sound to 4 (or 5 or 6 or 7, depending on the equipment you use) speakers.  If you want Quadrophonic sound, I would just go to your local stereo shop and buy a Surround Sound system and have the music play out of 4 speakers.  Thats what I use for my system.

If you want to save some money you can check out the Creative I-Trigue which cost $97 but there is a $30 rebate on them bringing it down to $67.  There is also this set of JBL speakers, http://www.newegg.com/Product/ProductList.asp?Submit=ENE&N=2010370060+70001616+50001460&Subcategory=60&description=&srchInDesc=&minPrice=&maxPrice=&ATTR1=&ATTR2=2010370060+70001616+50001460&ATTR3=\n\nLogitech has the Z-2300 set http://www.newegg.com/Product/Product.asp?Item=N82E16836121122 but the best speakers right on the edge of your budget would have to be the Klipsch ProMedia 2.1 at $150, http://www.newegg.com/Product/ProductList.asp?Submit=ENE&N=2010370060+70001616+50001390&Subcategory=60&description=&srchInDesc=&minPrice=&maxPrice=&ATTR1=&ATTR2=2010370060+70001616+50001390&ATTR3=

Any hobby radio / decent electronics shop (not Radio Shack) will have this.

any large retail store like a department store that sells any kind of computer stuff should have some in stock.  I know in the states a LOT of people use an online store called Newegg.com.  I don't know if it delivers there but they have pretty decent prices if they do.  All sound cards are easy to install as they are all installed the same way and come with instructions on how to do it.  I would personally look for on from Creative Labs called the X-Fi Xtreme music.  It may not be the cheapest but it's come down a LOT in price and it's really versitile (gaming, music, music editing and such) and has some of the best sound and features possible.  I can almost guarantee you that it will have better prices online than in a store.
