FYI - I live in the US (Seattle, WA) and ordered the 7s through
http://www.7-leagueboots.co.uk/ and got them the next day! Technically it was closer to 48 hours, but with the time difference they showed up on Thursday evening having been shipped Wednesday morning. I had placed my order on Monday. Just drop them an email and ask for a PayPal invoice and tell them what you want.
That said, shipping was a little messy - I had also ordered a bag to store/carry them in (which I'm glad I did). The stilts come in their own box, so they had taped the bag (folded up) to the top of the box and wrapped the whole thing in bubble wrap. It was pretty ragged by the time it got here, but everything was still in perfect shape inside. It probably would have been fine, but US customs seems to take special pleasure in ripping open boxes.
Anyway, it was a bit more expensive, but definitely worth it IMO - especially after reading the comparison thread on here.
Definitely make sure you also get the elite strappy things - they're a bit cumbersome, but do a great job locking your knee in place.
Oh.. and I couldn't believe how much trouble I had finding pads around here. I thought it was stupid to have pads shipped internationally, but after the ordeal I went through last weekend shopping for some around here, I wish I had just included them in the original purchase.
Hopefully this info is useful - I know how sensitive you guys are to pimping specific brands around here.
