First for the free options... Turn off your power on that circuit and find every outlet and pull them out and clean (Craigs Dexoit/Pro Gold) the connections on the back of the outlets and screw them down tight (they loosen up or were never tightened properly) Clean all your power cable prongs and IEC's in components and all connections while you are at it. If you can replace them with better outlets even better since your circuit will probably be in series so any loose connections especially grounds will degrade you sound. Next replace your outlet with at least a Hosptial grade 20amp outlet but ideally something better (Porter Ports, PS Audio, etc... tons of threads on this)
As far as conditioners Balanced Conditioners provide a smoother presentation (BPT, Platinium Power PP1, Exactpower, etc) and are transformer based.
Next regerators like the PS Audio Power Plant products and Exactpower (different model than above) don't fit in your budget as they sell for ~$1200+ used and the smaller one will only support your front end. I have found that these add dynamics, detail, weight, and sometimes the best detailed blackness level in situation where urban noise is problematic to the music. If you ever get a plasma,DLP, or LCD get a Regenerator and watch your eyes pop out at the improvement!!! plus your bulbs will last longer with the constant exact supply of power. Same thing for using a PS Audio Powerplant 300 with Tube wave on a tube preamp!!!
Finally you have filters types that are passive (Shunyata, PS audio Duete and Power Director Series) (These are a bargain and I would recommened a 4.7 or a 3.5 because of all the outlets and all the isolation it provides.), and the many other outlet style types.
Oh yeah you can also play with testing polarity for each component at this time to see which way a plug needs to go into the outlets. Check out Galen Carol audio GCAUDIO.COM for some excellent FAQ's about power problems. he's a great dealer also to work that has been around for years.
Good luck the fun is about to begin!
