As a web designer, I can say that the site looks great and is easy to use, it's doesn't even use html tables either which is a bonus for SEO. However, there are errors what could possibly be cut down on
link.
Ok here is the constructive critism, I wouldn't like 'l33t' in my business name, looks unprofessional, plus you shouldn't really use numbers in domains either, again looks unprofessional and 1990's.
I do like the clean style of your site, however, it is too simple if you know what I mean. Needs a little more colour and a little more 'going on'. Try to loose the blue font too, got to think ergonomically here and the fact is, blue is rather hard to read compared to other colours.
Overall, the site looks fresh, good functionality, simple, professional and ultimately, I would buy from the site (if slight changes were made).
