Used B&W matching on uber-budget system


I'm slowly scrapping together a *very* modest system, and could use a tip or two on speaker selection. I'm currently running some old B&W DM302's as my mains, and a B&W CC3 for my center channel.

I'd like to move the 302's to the back surrounds, and get another set of small and affordable (used) B&W for my front channels, something that will blend well with the CC3 which I'd prefer not to have to replace. I was thinking DM305's, but I don't see them up for auction very often here or on ebay. I was thinking maybe a pair of DM601's, 602's, or something of the like since I see more of them available used. Would something like the DM602 S2's blend ok with the CC3? Or would the CC3 just get overpowered?

I'm definitely trying to stay with something smallish, and let the Hsu STF-2 subwoofer I'm about to order handle the lower frequencies. Any tips as to some good old B&W's that would be an upgrade from the 302's, yet still work well with the CC3?

I have DM603-S2s and CC3, no problem with movies. For music, I mostly use 2-channel with the 603s, but I didn't notice any serious mismatch issue with the CC3 during the few times I've dabbled with SACD and DVD-Audio multi-channel.
This is both a HT and music system. I run it 5.1, but I do use stereo only for music generally, plus the subwoofer. My Hsu VTF-1 arrives next week, can't wait.

I think based on this feedback I'll probably be hunting for some 602 S2 or S3's, but I really need a decent receiver first I think. So much to buy...
By the way, WWW.AUDIOVIDEOLOGIC.COM has the B&W LCR 600 center channel speaker on sale at 40% off, that is reportedly $299. They also have two of the larger 600 Series main speakers on sale for at least 30% off (of course this is off new price). Also, available only via walk-in vs. the net. So this should give you some idea as to the values used on B&W speakers in this range.
I'm afraid I'll have to wait on the upgrades to the main speakers for the moment, found out that my 'el cheapo sony receiver had a hard wired sub crossover set at 150Hz, so I had to move up my receiver replacement plans before my Hsu VTF-1 gets here next week. Just bought a Onkyo TX-SR606 receiver cheap on ebay, should be good enough for my setup for a few years.

Thanks for the heads up though...
I am a newbie to Audiogon so please forgive me if this should be posted to a new thread. I am in a position similar to Dakster but I am starting with a pair of mint DM22s (circa 1981). I am trying to figure out whether to use them as rears with other B&W l/c/r and a sub (Hsu, SVS, AV123) or look for more DM22s for all speakers. They are tough to find in good shape. I too will be relying on a Onkyo 606 receiver and a tight budget. (Not to mention WAF and small kids).

All opinions on a center channel and how to best deploy the DM22s on a very limited budget are welcome. . .thanks in advance!
