Space Marine Bike Army

So ever since I started playing Warhammer 40k I have been in love with the concept of a bike army. I dont know what it is but they are just super cool. I have been experimenting with how to best use this type of army and have come across a very well done article detailing a bike based army. The main problem I had with it was these Land Speeders. I was not a fan. The low armor value really threw me off the band wagon. After reading the responses that Red Archer received, I think I may be ready to jump back on that band wagon. Of course the main problem anyone has with putting together a bike army list is just the cost to buy the models. Well here we go again because I may be buying 6 Land Speeders. Maybe just 3 to start out and if they work out well I may have to invest in 3 more. I may throw up a potential list in the future but for now I am still working on the details.
