Here are two points that I've realized. I think that the ThinkGeek website is pretty well-done, I mean they're in a relevant market as you guys, so you should definitely look into their website at: http://www.thinkgeek.com/

The elements are really aligned in a logical fashion. It's pretty aggressive on the eyes when you see huge yellow boxes with the prices on the right.

The stuff that's supposed to grab my attention, doesn't. "Invest in yourself: learn by doing. Read on to learn how the NerdKits philosophy is implemented in our kits, and why other electronics kits will leave you intellectually unsatisfied." is DISTRACTED by the "Updated Thursday, December 17th, 2009:" div.

sparkfun.com is more in line with what they do, also a very good site.

Your page seems very 1990s or early 2000s in its design. Either that or a manufacturer's B2B website, not a B2C like you seem to be marketing at.

I would highly recommend outsourcing your design to some place (even some place that could do it on the cheap).

The product looks amazing though!

I think your first step would be to get a designer to make it more visually pleasing, and then maybe consult with him or her about the layout of content.
