I've heard good things about CUL. But... no matter how good the program is, you have to weight the costs. London is an expensive city. The Tube is ridiculously expensive. The exchange rate stinks. I speak of all of this while in the UK and as I am almost 99% sure I'll be at a program in the UK.
A few things - do check out scholarships! Chevening, Marshall and Fulbright are all closed for next year. But there are some others - especially if you're a EU or UK national.
Also, when doing the math, think about how long a degree is in the UK versus the US. For me to do my Archives degree in the UK it's only 1 year versus 2.5 in the US so the slight uptick in costs makes sense over the course of one year instead of two years of full out-of-state tuition.
Ultimately, you have to go with economics. It sucks, but it's also the state of today's economy and really, just how the world works.
As for waiting and obsessively checking...I wasn't too too worried until I got my first acceptance. Now I'm like "Dude, X school accepted me, why can't YOU tell me the decision?" Needless to say, it isn't helping that one school's deadline isn't until tomorrow.
Also waiting impatiently to hear about my summer plans. All in good time. In the mean time, I have my senior thesis to write. Second term starts for InterPol on the 30th, for everyone else (my history class) on the 4th. In the meantime I've got to take one exam and spend some time in Cardiff and Bath.
