nuge, I suspect the 04s will be close in price to the 03s (don' t know positively). The Stalker is discontinued for 04. The Patriot single cam would be close ATA, as would the Liberty. The Liberty will have very similar brace height & speed compared to the Stalker. The Pat more speed & less brace. Both bows will be better shooters than the Stalker in terms of recoil, vibration, & noise due to the VFT design. If you want a top of the line bow, these are two definite considerations.
Oops, yes I install limb savers along with the Vibra Blocks. The Blocks have been redesigned for 04. So I' ll wait & see if it' s necessary on the 04s. No the string silencers don' t break off like Leeches. The silencers are also redesigned for 04.
