Well.... BTC-e is cheap and has been reliable so far.
Probably go with BTC-e too. They don't always have the greatest of rates but getting money into and out of the exchange has always been speedy and hassle-free (EUR, BTC, FTC and LTC deposits/withdraws so far).
They support a lot of external providers and the btc-e e-code things seem to be accepted by places.
What do you mean cheap? They should be roughly the same price, otherwise you can buy on btc-e and sell on bitstamp.
BTC-e is basically almost $100 to $200 and sometimes even more cheaper. Only in the USD/coin ratio though. If you are doing coin/coin, then the ratio is about the same as if BTC was valued at $1000.
The reason for the very cheap $$ prices is because it is nearly impossible to deposit any money there, so people are comfortable selling it for a cheap price. So they can get some cheap $$, and use that small amount of $$ already deposited to perhaps profit in the future.
So your saying that I can still buy BTC for $200?
he probably means cheaper than other exchanges. it's quite amazing how the rates are so close now.. $850-$870 between btc-e, mtgox, and bitstamp.
