Always cheaper to get what you want first. Keep your eyes open for used. All of mine were purchased used (BP7001 L/R, CLR1000b, and now BPVX's for the rear). I would not recommend the 7006's. The 7004's would be a big improvement(I've had them) but 7002's or even 7001 and 7000 would be even better. Keep an eye on CL and eBay. You will get way more bang for your buck buying used IMO.
