I alpha tested it before launch and IMHO it's a good site with good people and run very well by Mike Boydell. All sites have problems, but Mike is responsive, listens and acts when customers have problems.
Knowing Mike, it will end up the best site of its type, just as T2W is the best of its type.
I tried Money/am Level 2 offering, which is less than a third of the cost of Proquote. I very quickly found out why and gave up. It did not work properly and was a clumsy affair which required masses of screen space and comes complete with the added distraction of flashing adverts on your Level 2 information. Not a serious tool in my view. The site itself is much like the rest of the countless similar ones.
