Interprise and Tradepoint Enterprise

I am based in the UK and have read quite a bit about both of these products.

However, what I cannot find is any authoriative reviews / evaluations or even user opinions.

As these are both North American products, can you suggest publications that you trust ,that might have reviewed the products or even have opions yourself.

If you have an opinion, can you tell me your interest, e.g. are you a reseller , a user or an accountant.

Thanks.
