MX range mid/top cabs wanted!!

Hi.
Just wondering what the chances are of finding a pair of, or maybe four MX top cabs.
Would prefer MX600s but any considered.
To go on top of four BS600s.
Any condition considered also. In fact in need of recon prefered.
So, if anyone has any cluttering up their garage let me know.
I can't buy straight away as i need to sell the tops i have first but need to know what is available and how much money i need before selling them.
Cheers.
