text: Do you know about the component?(the performance,the way to configure it's and whatever).Just go to the main suplier by near you (don't go to the shop) coz the price will be high up for home user like us.Just get a members with them (supplier's).I'd the same like that to get a special price (i got a dealer price from  my supplier-it's means cheap than home user price)...just try it yourself & good luck...
