Anybody got any suggestions on what microphones to buy?

less than 80 quid would be best, standard XLR socket, and preferably dynamic.

i want bargains mainly, cos i don't want anything thats gonna break easy or be naff quality.

I don't usually like anything Behringer, but the Behringer XM-8500s are steals. They're copies of Shure SM-58s and I must say, they did not do too bad a job at coping this one. You can probably pick up 3 of them for the price of 1 Shure SM-58. Check it out.
More info, such as what you're recording would help(type of music, what instruments, acoustic/electric etc)
