more help with vinyl..

I posted on 11/02 and maybe one step closer to understaanding the complexity of tt's and music it produces. I have an old pioneer PL-516 with new belt & cartridge & 50 mostly used lp's. New Yamaha ax-596 amp with Paradigm speakers. 90% of my albums have much surface noise---pops etc.....newer stuff(mid-80's?) pop...that looks unplayed is ok. I bought the diskwasher system...no help. 2 weeks ago bought a great Ellington album.'59...looked great ..did the dw system again & again...only got worse.! I bought 2 new albums...played on my Kenwood system (new-2 years old and Pioneer PL_516) great! The Ellington record sounds bad on both systems...took the record to dealer in Spokane...auditioned Pro-ject 1.2....had seen reviews ..it sounded better but still bad. I bought the pro-ject 1.2 and will add a new cartridge (grado red) in about 6 months after I get this tt thing and vinyl figured out. I don't want to spend the $450 for machine but had hoped to save the 40 plus albums and restore them. It looks like I have to buy virgin or near mint records but most in second hand record stores look ok but still may sound poor (on my system)..am I right on this..? If this is right then I can only buy on internet or pay big $ for new records but at that cost maybe I should go for the convience of SACD, HDCD, etc. the cost differnce is not much over perfect LP"s. But once you hear great vinyl all your cd's sound so limited. Maybe the problem is I'm trying to do this on the cheap...? How do you get good vinyl sound for only $5-$10 per record...can you do this on my tt's...? HELP! What can I use on my records to restore sound..? anything..or give them to goodwill..? It doesn't seem to be a tt problem..a condition of my vinyl..? How do I keep my new ones from going bad...? I'm starting to get anal about this like you other guys...save me before it's too late...!
