How much woud a a used lapotop cost?$300 would solve your issues.Don't throw the baby out with bathwater.Your price point would make it dificult to get beter than what you found problems wih so just get a dedicated laptop.Plus you'll have possibility of Internet audio.A squeezebox and two $150 500 Gig HD's gives you music server ability to add lossless audio your record with second HD to back it up.For more than a used laptop a $600 Mac Mini add's ease and what many 'Philes are using for day to day play.Don't give up sound you like is my vote.Think of it this way you'll pay twice as much for a product that might not be as good as one you have found you like.
