Yep, since the move to exclusively fw planted, AE has replaced Aquatics Online as my number 1 site. I love the service that you get from Richard, very helpful, so much so that I don't mind paying the extra for some of the products on there.
I'd agree with the above-the best place in the UK for planted tank goods. Always responsive and prompt. The gear is top notch. I rarely use anywhere else. It isn't always good for you bank balance though!
