Has anyone sat in the Upper Tier at the O2 Arena, London?

I'm in the same predicament. I'm on a bit of a budget too and I've got MJ tickets for July but these were the only ones I could find that were Upper Tier (£50.00). As all the others have sold out and the next set of shows isn't until Feb 2010 I say sod it!.. If it's an artist you love then just be happy to get seats. I mean my tickets would sell for a killing but I'm still gonna go...Hey long as I'm in the Arena and see MJ I'm a happy Bunny. Plus when I bought them there was 3 sets of prices and only £7 handling fee..now that they've seen demand for tickets they've raised prices for all of them to be £75.00 and £9.00 handling fees!!! So my tickets are at least woth £75.00 each now!! But I'm like in BK 418 Row T which aint that great. But my friend said she sat in upper tier for a comedy show and it was amazing you can see the whole arena but it's very steep so don't sit there if you have a fear of heights!
