Bi amping a pair of B&K ST-140's


Hello all. I am building a second system and am looking for a pair of B&K m-200 monoblocks. I cant find a pair so I am thinking of bi amping a pair of st-140 amps. My pre does have two sets of main outs. Any other ideas? I thought of the adcom 565's, but I have always liked the b&k amps and their sound. Other thoughts were a b&k ex 442, parasound, rotel, etc. trying to keep cost under $1000. They will be driving a pair of b&w cdm7's.
Thanks all!

IMO, a biamped pair of ST140's isn't close to a pair of M200's (I have both). If you don't have the patience to wait for a pair of M200's, I might look for a Parasound HCA2200 (I've also had one of those).
Do you have the older or the newer m-200's? I actually found a pair of m-200's but they are the older model with the captive power cord and the rack handles. Are there any other significant differences?
I have the older ones, plus I have one of the newer ones that I use for a center SPL. The old ones are one of the best values around.

The difference is mostly packaging afaik. I also had mine nodded at musical concepts.
The guy that has them is asking $850 for the pair. Is that way out of the ballpark in your opinion?I really want them and know I cannot go wrong buying them, but I also don't want to overpay.
Thanks
Also looking at a nice Ex442 sonata. I'm thinking that would also be plenty of power for the B&W CDM 7NT's
