Doing prague on the cheap?

Any ideas for a cheap weekend away (flight and hotel etc)
Answer
Praha is expensive now (actually getting there and accom). about £70 for flights, and i recomend the ametyst hotel (£150). very nice . 4* and great service. praha itself is cheap. about £0.70 a pint. nice place to visit in winter (xmas markets, snow, coffee!). shopping is ok, not many places to go but theres a few malls and designer shops there. sights, a load! make sure you see them all! nice pizzeria near the castle, to the right before the bridge entrance. have fun!
