I've watched some of those DIY stabiliser videos too and thought I might try it. Then I found a site which sold a really decent looking one, but subsequently forgot to actually make the purchase. Now I can't find it! I think it was a Dutch company, but their sample video of a guy using one while riding a bike round some city streets looked very impressive. I'll have another hunt as it was selling at a very competitive price, round about £60, I think.
