Hi has anyone tried any of these T.Bone dynamic mics for recording?

I'm also interested in this condenser

I worked with a West End session band in London a few months back and they were using the T.Bone MB85 beta's and they sounded great live. I'm looking for a cheap dynamic mic for vocals to compliment my current:-

RODE NT-1a
MXL V67g
Studio Projects B1
T.Bone RM700 (ribbon)

I've also heard great things about the Shure SM57 and Sennheiser E840. These are out of my budget because I only have around £30 to spend.
